Are there any dealers out there in Southern California that can install the satellite radio for me? My car is prewired and since I dont want to do anything to it where the car would mess up me and my dad have come up to the decision that a dealer would be best to install it. If there are any dealers out there with a reasonable install price (considering its only a 30 min to an hour install at the most) please reply to this post or pm me. This would be greatly appreciated.
