I successfully installed 1.24 (non-modified TYP) to my 3790T but I can't seem to send the 1.24 (modified TYP) to my device. What I did was to use GMapTool by deleting the included TYP file (from the installation of the contributor map 1.24) in the working folder and replaced it with the one from post 9. I then opened GMapTool, added the working directory, clicked replace TYP file in image file, and clicked Change All. When MapSource starts sending it to the device, it returns an error of "there is a problem with this Garmin application, please contact support, etc. etc.). This did not happen with the 1.24 (non-modified TYP).
What could have I done wrong? Please help.
Thanks.
