Ok so when i was doing the heater core a few weeks back or a month ago now i think
i remember having the navi out of the car for about 9 hours or so maybe 10
and when i got it all hooked back up the
Memory setting presetting stations Memory points on the navi the clock it all was erased so had to reset it

the firmware was still on the unit just the rest got erased and deleted does that mean that the Battery inside the unit is bad

and that if im going to sell my unit all i need to do is
Unplug it for another 8 hours or so to let the theft lock clear so i can test it in the
Car of the one who is going to buy it from me this weekend possibly ?
