Garmin 76Cx does not communicate to laptop
mark_53
I bought a boat and the previous owner included a Garmin 76Cx and BlueChart version 5. Included was a copied CD with an older Mapsource version. I ran the setup.exe and it installed Mapsource along with the marine BlueCharts. I can see all the appropriate detail on the charts but when I connect the 76Cx to the laptops USB, the only option is to connect through Com1-4. USB shows no device available. I have a feeling I am missing Trip and Waypoint Manager. How do I get a copy of Trip and Waypoint Manager so I can communicate to the Garmin 76Cx? Is there another way to connect the Garmin so I can plot waypoints and track my route while boating?

Thanks
Boyd
You shouldn't need trip and waypoint manager. That was just a version of Mapsource bundled with a crude basemap that they distributed along with the older GPSes. For starters I would check the menus on the device itself, I believe it's like my 60csx and there's a Setup > Interface menu with a few options.

Try setting that to Garmin Spanner, then connect to your computer again and see what happens. It may be currently configured to send live position data instead of "talking" to Mapsource.

Thanks for the reply! Under Setup, Interface, the options I have are...

USB (Garmin Data Format)
Connected

Serial Data Format
Garmin
(Options for NMEA In/NMEA Out, Text Out, None)

Note: The Garmin serial data format is disabled when USB is connected.


I try the other format options and no joy.

I'm using a cable from a camera to connect the Garmin to the Laptop.

OK, I dug out my old 60csx and I see the same options. Guess I was thinking about the newer devices. However, since it says it is connected I think that your computer and Mapsource should see it.

There should also be a button at the bottom that says USB Mass Storage. Click that and see what happens. Does the device appear as a disk in Windows? If so, that should allow you to install maps on the memory card but will not access tracks and waypoints since you need "talk" directly to the GPS for that. If the GPS doesn't appear like a disk, then there is definitely a communication problem with your computer.

Either way, you may need to install the proper drivers. See this support article:

Ok, I select "USB Mass Storage" and drive H: appears in Windows 8 explore and see a "garmin" folder. Within that is a file called "gmapsupp". I click on that and get a message "This disc in\mage file is corrupted".
I loaded the new USB driver, reboot and Mapsource (V 4.12) does not see the 76Cx. How do I load maps to the 76Cx?

Mark does your 76 have micro sd card slot? If so you can build maps with Mapsource get free maps from gpsfilesdirect.com or buy Garmin maps and load the with mapsoure or basecamp.

Yes. It has a 1g SD card installed and I can see low level detail on the 76Cx. I have the BlueChart Version 5 Americas CD and can see them on my laptop using mapsource but cannot show GPS location on my laptop.

Put a 2 or 4 gig sd card in get a good card reader if your pc does not have one a 76 will only read 2034 or something close to that figure map segments. I use kingston sd cards. will send you a pm. Mark send me a email and I will send you some how to info.

Wait awhile here, we are mixing apples and oranges. On your device, maps are stored on a memory card. But that is the only thing on the memory card and in your OP you said you wanted to load tracks and waypoints. To do that, Mapsource "talks" directly to the GPS itself using a special protocol.

However by enabling mass storage mode, you have established that there is a good connection between the gps and the computer so we can rule that out.

I wasn't aware you were using such an old version of Mapsource. That is likely the problem, I think earlier versions were not fully compatible with Windows 7. Mapsource has been discontinued but the final version was Windows 7 compatible.

Update to the newer version here (6.16.3) and see what happens: http://www8.garmin.com/support/download_details.jsp?id=209

Mike - I think you probably meant gpsfiledepot.com and not gpsfiledirect.com.

Yes you are correct Boyd Thanks.

I updated to the new Mapsource but only low level detail appears and I can communicate to the PC. I try and unlock the BlueChart and the Garmin website install procedure asks for serial number and Product Key/Coupon code. I enter serial number off the 76Cx and 8 digit code off the back of the BlueChart Americas Version 5 but Garmin website says invalid Product Key/Coupon. So I removed the new version of Mapsource and reinstall the old Mapsource. That way I at least have the detail maps but can't communicate to the 76Cx. Is there another program that will allow me to use the Bluecharts AND communicate to the 76Cx?

Not for sure but have you tried Basecamp? BaseCamp will not work. I also use Garmin MapInstall.
Boyd
Really, the solution is to contact Garmin Support since you have the orignal disks. They should be able to sort this out for you. People report the best results when calling instead of e-mailing although you may have to wait awhile on hold. But if you are at your computer with the gps, they will talk you through whatever is necessary and can even remotely control your computer if needed. http://www.garmin.com/us/support/

AFAIK, Basecamp is not compatible with Garmin's marine maps. They want you to purchase another program called HomePort for that.

MapSource does not have GPS capabilities after v4.x or so. You should be using nRoute. You can get the last version 2.76 here:

If the maps don't unlock to your 76Csx, try GPS Gate.

Hmm, I just assumed you were trying to exchange data between the GPS and Mapsource. That's what Mapsource is for. But maybe I didn't understand this part...

If you want to see your vessel in real time on a moving map on your computer then Terry is absolutely right. Mapsource can't do that anymore, and hasn't been able to do that for a long time. nRoute should give you most of the capabilities of the old Mapsource.
