Got to call Kenwood to get the install code. You will need the serial number off the radio.... it is a real pain when you change a battery in a car.... if you ever have to do that get a good battery and a set of jumper cables, insert each cable end into a latex glove and punch a hole in the tip, ( this will allow you to hook up the battery and not worry about sparking off the car frame while trying to remove the old battery and keeping the good battery hooked to the cables. Ps. You would have 3 batteries total.... the one being taken out, the one going in and the extra one keeping power going to the car through the booster cables.
