I started having a problem with my unit a few days ago. It started with the navigation screen being messed up a day or so earlier then now the unit starts up with the please wait message on the screen and I can get everything to work except for the navigation part for about 3 and a half minutes then the unit resets again. I tried to look at my files with test mode but I can't access the apl2/igo folder. It just keeps on looping back to the flash drive screen. So I end up with apl2/igo/apl2/igo/apl2/igo continuously. I'm on the hacked 3.0 firmware and have some other mods like Idt skin and the blue theme. I'm guessing I need to probably reset the device back to factory and reload everything? It's just odd cause I haven't modded it in about 6 months and it has been working good for over a year. I also checked the system settings and it says "no map version".
