I have a f700bt and it is running 3.0 firmware. I had Abb's Chrome Nav Mod 'All-in-One' V4.0 And one day I changed my car on the gps and when I did the unit restarted. Since then everytime I click the map button the unit will just restart. I had the 3.0 installation handy still so I copy'd the APL folder over to the unit hoping that it would fix the problem? but it didn't so I need some help. Can I just delete everything on my unit and re copy all of 3.0 over again?
