I'm looking for someone in the Southern MD or SW PA area who can install audio components I plan to purchase for a 2007 Prius: XM Direct satellite radio module to work with the car's satellite-ready radio. VAIS 2L2i and SL2X components to integrate an iPod and the satellite radio as part of the navigation system. Shark fin antenna. Any suggestions would really be appreciated. P.S. I am an electronics imbecile.
