Don't know - I skipped disconnecting the battery, though that's not the right thing to do. They make a little cigarette lighter adapter that accepts a 9V battery for maintaining radio codes. Not sure if it's required to do that on our cars. Unlike the E46, I don't think I got radio codes with this car.
