Thread: Help needed!

Usually, you have to rename exe file (MobileNavigator_9.6.13.405512WD.exe) to name it was used (Primo, Navigator...etc).
Then, you need to preserve the file structure as it was! What was in "data" dir? What was written in the "shell.ini"? What in "sd.ini"?
And, few more things:
- it is 3.5", low res, you can not use Primo 405512. Find proper version (320x240 I guess, but...).
- Most important: what was original version of software on it? Maptrip 2.6?
The big problem with dedicated devices, usually are locked to a particular type of firmware, and software. It often fails simple software replacement, you need to unlock the device first. But, you can try.
