I followed the instructions that you have for this install, but when I get to step 5 and reset, nothing happens. My unit just comes back up with the splash screen; I can get to the "top menu" but then nothing responds. I hit "settings" and go to system info and it shows version 2.06 and for map version, it says "no maps loaded" When I try to get into testmode (with another sd card that has the testmode files), it gives me a 'windows-like' screen that looks like it's copying something then the system goes blank. I don't have a clue what to do next. Any help would be greatly appreciated.
