Thanks. I tried the first method.

I haven't tried it with the original SD Card. VMS want me to send the old SD Card back to reload all the offroad maps as its crashing but I was hoping to get a replacement SD Card while they it is away. Also eventually the map updates will stop.

I think it's a firmware issue.

I deleted the "drive" folder. I renamed the Offroad GPS program folder to "drive" Then I renamed the Offroad GPS program to "drive.exe". But when I tapped on Street it crashed too even though it runs fine if I rename it back and run it from Offroad.

Possibly the "Street" button does something else besides running SDMMC\Drive\drive.exe. It doesn't looked like it is signed any particular way.

Also there doesn't seem to be anyway to access the Operating System on it to verify what it's doing.

Thanks for the help.
