Thanks for the help i really think i need the new garmin board. I was really hoping someone might know a solution for factory reset. tried the fuse, removing battery etc and the radio does reset but not to factory, all presets Sirius and settings stay. I remove battery cables and clamped them together for 3 hours
i have tried several usb and i did try the gmapprom alone. Right now i am using a portable garmin. everything else in the radio works great.
