Intermittent and repeated crashes using MS S&T 2009 with a CanMore GT-730F(L). The error message reads, "The Instruction at 0X00XXXXXX referenced memory at 0X0XXXXXXX. The memory could not be "Written".
My setup is as below:
Computer
Dell Mini 9 w/Atom 1.6 processor
64gb RunCore SSD
2gb Kingston Ram
Fresh install of XP Pro
Fresh install of MS S&T 2009
GPS
New CanMore GT-730F(L)
Remoted by high quality 6" USB cable to dashboard
Internal Baud Rate set at 38,400 with no real way of changing.
The CanMore seems to be very sensitive. If I turn it on in the garage I normally have acquired 7 to 11 satellites by the time I've backed out of my driveway.
When S&T is working it does great. Speed and direction changes are very quickly reflected. And the positioning is actually better than I expected. However, it may work well for several hours and then crash several times in a short time frame. There are no physical explanations I can think of as far as tall buildings or other obstacles to block the signal. And strangely it seems to happen more frequently at slow speeds than when driving at highway speeds.
I have removed and reinstalled S&T without a change.
I have played with the Port baud speed changing it from 14,400 to 38,400 through my Device Manager. And changing baud rate made no apparent change either in the tracking or the failure rate.
The computer has been all but flawless except for this. Videos and some fairly hefty databases run without a hitch.
I can typically resolve these issues myself. But this one has me stumped.
I wish I had either a different GPS or a different tracking package so that I might eliminate one or the other.
Does anyone have any suggestions I might try at this point??
I appreciate the help!

If the GPS can't do 4800 bps, it won't work with Streets & Trips. Changing the COM port settings will not resolve the problem. You will have to use GPS Gate to mediate between the GPS and S&T or use a different navigation program.

I appreciate the response but according to the technical data on the MS Web site MS S&T 2009 recommends 14,400 baud or greater.
The 14,400 baud note refers to the minimum speed of a modem required to transfer photos. The technical information, such as it is, makes no mention of the GPS data rate, only that it must be NMEA compliant. However, 4800 bps is a requirement.

tcassidy,
I checked with the seller of the CanMore and although the user's manual states the default bps is 38, 400 the CanMore is actually set at the factory for 4,800 bps. I adjusted my port settings and have experimented with it this week. I'm still getting random crashes with S&T.
I have noticed that it does tend to fail more frequently when I'm using a 6' extended USB cable than when using the 4" dongle that came with the GPS. This suggest a possible comunication error between the GPS and the USB input. I've tried it on all three of my USB ports and that doesn't seem to make a difference.
I'm a little disappointed. The CanMore seems incredibly sensitive and acquires a signal readily. But perhaps it is a little too sensitive and getting interference from other sources.
I'm considering perhaps getting a bluetooth receiver and giving that a try.

I can't see any reason why your GPS would not work with S&T at 4800bps and a 1 Hz update rate. Is there another program you could try it with in case the problem is not with the GPS?
Terry
Terry
Terry,
Thanks much for your response. I actually tried a little program called GPSDiag on the way home this afternoon. I was traveling about thirty miles over a secondary highway in the country. The GPS was on my 6' extension USB cable and I was getting great signal bar strength on a minimum of 9 and usually 11 satellites. Suddenly one of the bars went full red indicating a loss of signal and all of the other blue bars quit responding at the same time. At that same time the red bar stayed on red and could only be cleared by shutting down then restarting the program.
The driver that was included with this GPS is the PL-2303. I've just downloaded a newer version of that. I then uninstalled the old driver; rebooted; and installed the newer driver. If this doesn't resolve the issue I think a faulty GPS is the most likely cause.

That is a data logging GPS. Do you have a program to download the tracks to and check them?

I have a very similar setup. The only difference is I don't have the (L) version of the Canmore. Unfortunately, I am getting very similar results. Almost every time I use Microsoft S&T it crashes at some point.
My question to those out there that know more about this than I... If it was a communications issue with the GPS antenna why would it crash Microsoft S&T? Why wouldn't just say "GPS signal lost"?
Up till now, I was thinking it was a software issue.
BTW - Other GPS software installed on this laptop requires a rate of 4800 to work.

It is possible that occasionally the GPS is passing a sentence to Streets&Trips that it can't deal with.

What other navigation software do you have on your laptop? Street Atlas, Mobile PC and iGuidance - for example - will work at data rates beyond 4800bps.

Terry,
I have a program called GPS Viewer that I ran this morning on the 30 mile drive to work. I watched the data stream and didn't see any evidence of failure and the program functioned the entire trip. I ran S&T all day in my office today without a single problem. I was picking up 5 to 7 satellites from inside the building. I've also run S&T all night from my home office without a failure.
This afternoon on the way home S&T locked up three times. This appears to be a problem only when I'm in motion and usually when I'm changing speed. I've checked my system resources while sitting still and CPU usage varies between 4 and 12% and memory usage is minimal.
I've got another laptop coming in a few days. I'll load a trial version of S&T on it and run it to see if the error repeats.
Thanks again for your help!

I'm running it on an iTronix GoBook. It has an ATI Mobility Radeon 9000 graphics card set at 1024 x 768 (32 bit color).
No I have not let it run for any extended period of time, without moving. I will try that tonight. I'm also going to try plugging the GPS antenna directly in to the USB port (rather than using the extension cord).
Anyone have any suggestions for an alternate GPS software that has a free trial period. I don't want to buy anything until I verify that it works. Also will be looking for suggestions on PocketPC software and the best marine navigation software (sailboat) soon.
Thanks
kblakely, welcome to Laptop GPS World.
There are a couple of things I'd try. None of them may necessarily help, but I'd try them anyway (since nothing better comes to mind now):
1. See if the manufacturer of the USB GPS receiver provides an updated version of the software driver on its website;
2. See if placing Franson GPS Gate between the USB GPS receiver and Microsoft Streets and Trips may help

Marvin,
The driver the CanMore uses is a PL-2303 file. I actually found a more current version from a Google search and installed it.
Unfortunately it didn't resolve the problem and the seller maintained that I'd committed a really terrible sin by replacing the driver they provided.
This CanMore appears to be a really great GPS so long as you don't actually try to change location while you're using it!

1. Test the driver available at <edit>Expired link removed</edit>
2. If the driver doesn't solve the issue, try Franson GPS Gate
2. If the driver doesn't solve the issue, try Franson GPS Gate
I bought the CanMore from BuyGPSNow and that was the driver I had on there initially.
I think I'm going to wait until the new laptop comes in and I can eliminate the possibility that this is something other than a GPS failure. If, as I suspect by now, the CanMore has problems I think I'm going to try an i.Trek M7 in which case I'll get the GPSGate included through Semons.
BTW...your site has been very helpful and I've learned a great deal here.
Thanks much!

Kaba, you can download a 14-day free trial of GPS Gate to test, if you wish.
The iTrek M7 is a great GPS and will work directly with S&T as long as you have Bluetooth. Used in USB mode, the output is fixed at 115k bps so won't work with S&T. You would need to use GPS Gate in that case. The USB driver is superior to the PL-2303 generic one in that it allows you to use a different USB port without it forgetting it is already installed.

Last night I let it run all night with the GPS plugged into a 12" USB extension. It did not crash while sitting.
Today, on the way to work, I plugged the GPS antenna directly into the USB port and it did NOT crash. Now, one success does not make a solution but I'm thinking it's the extension cord.
I'll need to use it more both with and without... to verify.

There have been many problems reported when people try to use cheap longer extension cables in order to locate their receiver and laptop in optimal positions further apart than the stock cable allows. So it's reasonable to assume a flakey standard cable will also cause trouble.

I am officially giving up on the CanMore.
I have tried it on two different computers; both new; one with XP Pro installed and one with XP Home installed.
I have tried it connected directly to the USB port; on a 4" dongle; on a 2' shielded cable; and on a 6' high quality USB cable.
I have tried repositioning it in various places in the truck.
I have turned off everything possible in my truck to avoid any interference.
I have uninstalled and re-installed MS S&T.
I have uninstalled and re-installed drivers.
I have adjusted configuration settings on my computer.
I have even downloaded and installed GPS-Gate.
Nothing has resolved the problems I'm having.
I am still impressed at how quickly the CanMore can acquire signals. And even when my truck is parked in my garage it will eventually get good enough signal to get a lock. And, so long as I'm stationary, it will give good signal for as long as I have it turned on But I've never been able to drive more than a few miles without a failure.
I'm a little embarrassed really. I have a technical background. At various times I've worked on depot level

equipment repair. I've worked as lead technician on AF flight simulators. I've worked as supporting technician in an AF weapons development lab. And now in my second career I'm doing network/desktop support for a state agency.
With your background and all that testing, I am surprised you still believe the only possible solution is to replace the GPS. Have you tested it with other navigation programs? Have you tested your S&T setup with another GPS?

Terry,
I wish I had access to another receiver. I've asked my friends and co-workers and no-one has one.
I've read on at least two other forums were people have used laptops like mine with S&T installed without a problem. I also tried using both the CD install of S&T I had purchased and the trial version that I had downloaded. Both installed smoothly without any difficulty. But to answer your question no, I really didn't try it with another navigation program. But I did try it with two different little utilities, GPS Gate and GPSDiag and experienced hang-ups where there appeared to be intermittent loss of signal although neither of them actually crashed.
Using GPSGate today I got a new error message from S&T. (This as opposed to outright crashing which it had done previously.) I didn't record the exact message but it was something like The data received from your GPS is not NMEA compliant.
I've just ordered an M7. I should know fairly quickly whether the receiver is at fault.
Thanks much!
I have to agree with kaba. Earlier I reported success plugging the CanMore directly into the USB port. Although I have had 20 minute trips with now crashes... it has crashed in this configuration, as well. I'm looking for free demo versions of other software packages to try it with but have decided to go with CoPilot 7 on my PocketPC for navigation.
Still looking for Marine Navigation software that might work with the CanMore GPS though.
Kaba - Let us know what you find out with the new GPS

The iTrek M7 is an excellent GPS. I hope it assists you in resolving your problems.

kblakely,
Thanks much. I hope the Canmore will work well with whatever marine applications you may find. I think it is probably a very good concept. It was always very quick to acquire signal and when working was dead-on for speed, azimuth, and position. It just wasn't completely tested and debugged before it hit the market. It is something that could probably be fixed with a firmware update so I'm going to keep it for now.
I was very tempted to buy the iTrek Z1. I like the solar re-chargeable aspect of it and it appears to have the same basic chipset as the M7. But the M7 has 51 channels as opposed to 32 for the Z1 and I could find very few reviews for the Z1 which always makes me a little shaky.

How are you providing GPS information to Copilot on your PPC?
Several marine programs are discussed on the site. They should work with your Canmore assuming it works ok.

Terry
kaba,
The difference between 32 and 51 channels is just market-speak in my opinion. How many satellites do you expect to see at any time? The program just uses the best 12 anyway. you probably aren't seeing as many reviews on the Z1 as it would be a smaller market. Power is not that big an issue with BT GPS.

Terry,
You are of course right about the channels. The most satellites I saw on the CanMore was 12 and that was very rare. I had actually trted to buy the Z1 online at Semsons. But they are apparently out-of-stock or at least I was getting a consistent error message. Another online mefchant had them but they were priced $50 more than Semsons.
I found a used one on Craig's List but it was actually a little higher than the new one and I am reluctant to buy from a distant seller without ratings.
The M7 will serve me well. And the lack of solar panel is probably one less potential point-of-failure.

I am having similar problem having daily multiple crashes. Sometimes it crashes 3 or 4 times immediately after activating the GPS and other times it will go for hours before crashing. I have the Canadian Version with the Blox GPS model 1372. For past 2 weeks I have been trying to figure out why I am getting daily crashes. I might have it narrowed down to using the GoTo feature. I will admit, I am using the USB extension cord and will try to remove this tomorrow to see if it helps.
My options seem to be...get a new computer, go back to previous version of S&T, stop travelling, or purchase a competitors product.
Any help would be appreciated. I Love the 09 version and do want to continue using it.

Keep the product. Replace the GPS. Although I never experienced any crashes due to S&T or that GPS, it is not high on my favourites list. Try finding a good, inexpensive USB GPS like the GlobalSat BU-353. It will work fine with S&T. As to whether it will solve your crashing problem, I can't say.

Hi Obi-Wan Kenobi,
Welcome to Laptop GPS World.
Instead of reverting back to previous Streets and Trips software version, why not just trying the earlier version of the USB GPS receiver with the current software version?
Edit: Terry and I were typing at the same time.

I used my older GPS from the 2006 edition of S&T. The short trip this am to downtown New Orleans was successful. By that I mean it did not crash. I will have to wait till Monday to give it more of a try out. Last night I loaded up my CoPilot and used this 2006 gps and it crashed while I was stationary.
Thanks for your suggestion.
Thanks for your suggestion.
It may be a good idea to watch for a release of an updated driver for the CanMore GT-730F(L).
Hello,
Well, I think I have found a solution to the problem! The problem is not in the GPS itself but rather in Streets & Trips because S&T apparently crashes with some NMEA messages which include satellite information ($GPGSV and $GPGSA). The same problem was occurring with other type of GPS units as described here:
http://franson.com/forum/topic.asp?TOPIC_ID=4037
Fortunately, you don't need GPSGate to solve it (although you can use the solution provided in that link too). Just open Skytraq, connect to the GPS (Make sure that the baud rate is 4800) and go to the Binary -> Configure NMEA Output. Once there, set the GSV and GSA intervals to 0 and save configuration (I saved both to SRAM and SRAM+Flash just in case). After that you should not see any entries with $GPGSA and $GPGSV in the Skytraq console. Please note that if you go back to the NMEA Output configuration, it doesn't show the interval set to 0, this seems to be a bug in Skytraq.
After that Streets and Trips works perfectly!
Good Luck!
Humberto

Hi Humberto,
Welcome to Laptop GPS World, and thanks for the information. My BU-353 does output $GPGSV and $GPGSA, but I haven't experienced any issues running Streets and Trips 2009. What would I need to do to recreate the problem? How long do you need to run S&T for it to crash?

Hello,
Well, in this case this problem occurred specifically on the Canmore GT-730F, so you would need one of those units to replicate it (although I could send you a recorded log that you can replay using GPSgate if you want).
How long does it take to crash S&T? From my point of view, this is totally random (although it seems to appear more quickly if you enable navigation or the gps trail). Using a pre-recorded route I could never find a pattern. Sometimes S&T would crash at a particular point in the route and the next time it wouldn't. One thing is for sure, once I filtered out the $GPGSA and $GPGSV codes (first using GPSGate and then Skytraq) the problem disappeared.
Maybe the $GPGSA and $GPGSV codes produced by your GPS unit are different from the Canmore ones and they don't crash S&T? Here's what the Canmore ones look like:
$GPGGA,152221.013,1917.6879,N,09909.2541,W,1,08,1.8,2276.9,M,-9.0,M,,0000*63
$GPGSA,A,3,29,24,12,30,18,10,02,48,,,,,3.7,1.8,3.2*35
$GPGSV,3,1,12,29,66,333,37,15,57,109,04,26,53,119,09,48,47,247,39*78
$GPGSV,3,2,12,24,45,000,29,01,32,259,29,18,31,246,31,30,31,224,34*79
$GPGSV,3,3,12,10,25,035,20,05,21,198,21,12,20,190,34,02,11,084,16*7A

Using a pre-recorded route I could never find a pattern. Sometimes S&T would crash at a particular point in the route and the next time it wouldn't. One thing is for sure, once I filtered out the $GPGSA and $GPGSV codes (first using GPSGate and then Skytraq) the problem disappeared.
Maybe the $GPGSA and $GPGSV codes produced by your GPS unit are different from the Canmore ones and they don't crash S&T? Here's what the Canmore ones look like:
$GPGGA,152221.013,1917.6879,N,09909.2541,W,1,08,1.8,2276.9,M,-9.0,M,,0000*63
$GPGSA,A,3,29,24,12,30,18,10,02,48,,,,,3.7,1.8,3.2*35
$GPGSV,3,1,12,29,66,333,37,15,57,109,04,26,53,119,09,48,47,247,39*78
$GPGSV,3,2,12,24,45,000,29,01,32,259,29,18,31,246,31,30,31,224,34*79
$GPGSV,3,3,12,10,25,035,20,05,21,198,21,12,20,190,34,02,11,084,16*7A

Humberto, there are a few members of the S&T development team who have accounts on this forum. Your recorded logs could be quite helpful in getting the cause of the crash nailed down. Even though it doesn't crash consistently or in the same place, sounds like it will definitely eventually crash.
A good repro is like gold when debugging software. Considering that a workaround was only found after 39 posts, along with a considerable amount of detective work from you and many other technically-adept people, this could eventually save someone a lot of time. (The fix may or may not make it into S&T 2010 this year. But who knows?)
They only post here sporadically, so if you want to be proactive, you can find them by searching for the Microsoft legal disclaimer string: "This post is provided as is." You can then send that user a PM, which should get a direct email through.

Please help. Exactly where are these changes made? In S&T options, in Device Manager, or wherever/whatever Skytraq is as per Humberto's instructions? I have S&T(2009) with identical problems with the GT-730F. How do I actually access these fields to make the following changes? Eg., How do you open Skytraq?
"Fortunately, you don't need GPSGate to solve it (although you can use the solution provided in that link too). Just open Skytraq, connect to the GPS (Make sure that the baud rate is 4800) and go to the Binary -> Configure NMEA Output. Once there, set the GSV and GSA intervals to 0 and save configuration (I saved both to SRAM and SRAM+Flash just in case). After that you should not see any entries with $GPGSA and $GPGSV in the Skytraq console. Please note that if you go back to the NMEA Output configuration, it doesn't show the interval set to 0, this seems to be a bug in Skytraq"
Thanks for the help.

Thanks for the help.
I am not familiar with the product but Skytraq is probably an external program (on your cd) that allows you to access and modify the internals of the GT-730F.

I've been all over the net trying to fix this problem and I must reply to Humberto since I've seen his SOLVED! Post in quite few places. I do have the same problem as other users with the Canmore GT-730F USB GPS receiver, this Unit in my own opinion is $hit! with or without the extension cord will give the same results, I have done what Humberto's suggest with some results, Streets & Trips 2009 and Mappoint 2009 don't crash anymore but the reception of the Unit SUCKS! It will acquire a fix in seconds but you can drive on a street and the GPS will be half a mile or mile away from the point you are. I live in South Florida, flat like hell, no buildings, no tall trees, it's just grass man and it sucks!
I do have many laptops, Great laptops for this,all of them have both S&T09 and Mappoint09 I am a truck driver and have many USB GPS like the LT-20 from SA09 from Delorme(it rocks) I also have a BU-353 not bad. The Deluo ones ROCK baby but they are $pency.
All of mine have the regular USB cable but I actually need one that is really good and small like, NO CORD! but man they all suck, I gave up on the Canmore but I am still looking for a small Unit like that.
If any one have tested FOR SURE a small Unit and has some good recommendations,please share it with me.
I forgot to mention that I also tweak a little bit with the Canmore Unit,also change the Baud Rate as the sales guy suggested and try different settings with Skytraq to no help available,the Unit Sucks! I will not recommend anyone to buy this GPS.
Sorry to have my first negative Post.
Note:I have 3 laptops,HP Pavilion,Dell Latitude and Acer Aspire all 3 have XP Pro SP3 1GB of RAM and also Have installed on all 3 laptops S&T09, Mappoint09 and Street Atlas USA 09 which I have not tested it yet, I just don't like the way it looks, hehehehe.
