Still getting alot of requests on how to upgrade map so I figured I would just post it here.
Go to a torrents site and download Garmin City Navigator North America NT 2012. Make sure it says it’s unlocked. Also download “Jetmouse”, this is a key generator (you will have to turn off any virus software when you run it”.
If you cant find one unlocked download "gimgunlock" and drag your img file and drop it on the exe file. Should see a scrolling screen appear.
Open Jetmouse and put your unit id at the top. Down at the bottom click the down arrow (select map product) and click custom mapset. In the little box that opens mapid or FID = 2630 and PID = 1 other two leave blank. Then click ok. Then click the generate button a few times and write down a few keys.
Get a flashdrive and format it for FAT32 and create a Garmin folder. Inside the Garmin folder put the gmapprom.img file. Plug it in to the usb port and turn on the car. If you get lucky it will say a newer map was found and ask for the 25 digit key.
I had to download 4 or 5 maps from different places till I found one that would work. When I plugged in the flash drive it would read it for several minutes then give me an error. I downloaded everything from [Please Register or Login to download file] but you have to create an account to download.
The problem I'm getting is that I get an error instantly any time I plug in my USB stick, it says "Error on Reflashing
Error Code : 0x 31A1" and never actually tries to update. Anyone have any experience getting past this error message? 5274
