I have to disconnect the negative terminal from my battery in order to install a rear deck spoiler due to the trunk button & rear camera relocating. Anyone know what I will be facing when I reconnect the battery?
Seat presets, radio presets, phone books, pairing, Nav settings, what will I lose? Will I still have a nav & phone address list?

 

You'll lose seat presets, trip meter, and auto-window up/down (have to reset by holding window up for 10 sec, then putting it down and holding for 10 sec). Other things like pairing and radio you won't lose. Not sure about nav since I don't have one.
