Hello to you all This is a GPS unit under the brand of Mappy - road services in France. It's a 5 inches unit that runs WinCE 6.0 on 128Mb of RAM. I've played around in the registry, trying to make it run a custom application from SD at start up instead of Launch.exe, the executable that launches the unit's interface. Now I'm stuck with it at the start up erroe : File not found and the unit is in mass storage mode, therefor not activesync connection. I don't know which files I should put to run on microSD to bypass the Launch.exe sequence. I've tried autorunce.exe, I've tried with Mappy folder in which I've put Mappy.exe and Mappy.ini files (created previously with MortScript). Nothing. If someone is willing to help me on this one I'll be forever thankfull
