Follow the direction to get your radio's s/n and post the request
in this thread
You'll have to register over there first but on most accts, the 4 digit code you obtain from Loren will hook you up.
For future reference, write it down on the option sticker under the front hood, the label on the radio chassis and in the owner's manual. It might already be written down there too so check
. Some dealers will give it out at no charge w/ proof of vehicle ownership. Mine does, but not all do and you must take the vehicle in w/ owners card, etc....
Good luck
