It doesn't matter whether you have a route going in S&T when you have one going in Mobile PC. The fact is that if you have them both tracking your trip they are both running and using CPU cycles and making disk reads and writes and other such things.

Microsoft is so not noted for their programming efficiency. So if you had S&T running at the same time as you were running a route in Mobile PC that would be all I would need to suspect that S&T was hogging cycles and interrupts and thus slowing down Mobile PC.

I would be interested in knowing if there is a difference in recalc times when you run a route in Mobile PC with and without S&T running.

OK, I did some testing. The problem seems to be intermittent. I tested routing to the same point with Mobile PC running as the only GPS app and also running along with Streets and Trips. The results were the same, aprox 10 sec. Later I tested the exact same route in Mobile PC and there was a significant difference with a considerable delay. No variables had changed. Nothing else on the netbook was running - no virus scan, malware scan, etc. GPS in same position.

For the ones with noticable lag, is it possible the computer had been sitting long enough for the hard drive to go to sleep (powersave setting) and, thus, took some time to spin up before things could get rolling?

These programs don't always have all the necessary code loaded in memory all the time. Just as Windows swaps program code in and out as it needs it (pagefile.sys), programs also swap parts of themselves in and out as needed. That's why you often see a program folder full of DLL files instead of just one gi-normous EXE file.

So delays like that are sometimes a function of the disk drive having gone to sleep based on the powersave setting and the application can't do the requested function until the disk drive spins up so one or more modules can be loaded.

Also, on a system that doesn't have much RAM, like a 1GB netbook for example, it takes a bit of extra time to reload the application into memory from the swap file if you've been doing other stuff in the meantime that may have caused the application in question to get swapped out.

Just tossing out ideas to see if any might fit the profile.

No, it hadn't gone into any powersave mode as I was using the netbook continuously and Mobile PC was running the whole time. In fact, it was the only app running. (It has 2GB of ram. The first thing I did when I got the netbook was add extra ram and my clean install of WIN 7 Premium sees both gigs.) The very first time I used Mobile PC in the car it took forever to calculate and dropped the route completely when it had to recalculate and it has done this a few times since. Not a good first impression.

I don't know. I'm just not overly impressed. It's probably just a personal thing as I don't like the look and feel of it. Maybe it's picking up my vibes! (I'm trying very hard to like it as everyone else just raves about it!)

Thanks for the help though!

For what it's worth, I installed Mobile PC for the first time yesterday on a 5 year old laptop (XP) with 1/2 gig of Ram.

I had a separate Nuvi 255W running alongside the laptop as I took a familiar 12 mile route to a family member's house. This route always requires a "recalculate" on any GPS due to the shortcut I take.

Mobile PC did the recalc in the same time as the Nuvi which was pretty quick, like a matter of seconds.

I noticed that when default zoom levels are used, the laptop version (Mobile PC) was able to display a lot more street names as I drove through a neighborhood than my Nuvi 255W.

One possible difference in our setup is that I am running the Garmin USB GPS receiver. Even though you may not have had MS Streets & Trips running - I believe you mentioned at some point sharing a single GPS unit between the 2 programs.
My luck could be the result of a simple connection to a receiver made by Garmin for use with Mobile PC.

So, are you saying that GPSGate may be slowing down the calculation time?
Bob Harvey
Well, I am a newbie on GPS Gate issues (never needed to install it). So others would know better if it "could" be the issue.

My observation is that we are both running the same applications, and that is the one difference. I am not sharing a GPS receiver between the applications.

You did mention that the problem also happened when NO OTHER APPLICATION WAS RUNNING, so my theory may be wrong.

BTW thanks for posting the setup with Streets & Trips on the left, Garmin Mobile PC on the right side of the screen. That seems to be working great for me. Each of them has their own GPS receiver, running on a laptop with plenty of USB ports.

I have to use GPSGate to get my Garmin GPSMap 60CSx to work with GMPC, so I can't really test it without GPSGate. Oh well!

Glad you like my dual apps idea! I like it.

You haven't updated GMPC to 5.00.70 yet? That is supposed to resolve problems of that nature.

Karen,

I've tested and both my GPS10x and my eTrex Legend HCx are working with Mobile PC 5.00.70. Garmin's update notes say that the upgrade now allows all of the "X" units to work with Mobile PC so your 60Csx should work fine without GPSGate now if you want to try it.

Yep, I know you need GPSGate to share the GPS receiver but just so you'll know that you won't need it when you only want to run Mobile PC.

Hmmm...just upgraded last night....will test.

UPDATE:
I have revised my opinion on Garmin Moble PC. After upgrading to ver 5.00.70 AND purchasing a new receiver (GlobalSat BT-359), I have noticed a SIGNIFICANT change in calculation and recalculation times. Route calculation is much faster and recalculation was almost instantaneous. Unfortunately, I don't know whether the ver upgrade or the different receiver made the difference as I did both at the same time! (Never introduce 2 new variables at the same time.)

I was always surprised that Mobile PC seems to take as long to calculate a route across the street as one across the country. I didn't notice a great improvement with 5.00.70 but the GPS (assuming you have a lock already) makes no difference.

I have nRoute and MapSource Topo 3.02 working, and I just received MapSource MetroGuide V7, and when I open V7 in nRoute I get a box saying:
Quote:
Product restrictions are placed on Metroguide NA V7 due to license restrictions. These are: No turn by turn directions.
How do I get by this?

Hay, I'm not to sure witch GPS software to get for my computer. Any advice?
