I have a VMS 700HDX. It runs igo for the street navigation part, the maps installed with it are locked to the SD Card it came with.

I've swapped SD Cards and was trying to install a copy of igo that wasn't locked to the device.

Currently it's in a folder called drive and the executable is renamed drive.exe.

Any copy of igo I install except for the original one crash before botting saying it can't find function drive.map.

I have completely deleted everything in the drive folder and just installed igo and made sure there was no sys.txt or save folder in the copies I had installed and only had the basemap installed.

Given that the file is named drive.exe did I need to fix namw that anywhere else? Or is there something else I need to do? Is it possible that it can't run another version than the version that is installed?

Any help is appreciated.
