Radio combo for aftermarket radio installation in factory radio location. Radio kit, wire harness, and antenna adapter. Black color radio kit. Designed specifically for the installation of Single or Double DIN radios. What's Included? 1. Radio kit. 2. Wire harness. 3. Antenna adapter. Important compatibility notes: Wire harness won't work with vehicles with premium system- no Bose, no factory external amp vehicles only. Will require you to run a separate 12 volt ignition power wire to the new radio's factory wire harness since that wire is not available on the factory harness. Will not retain some features that go through the radio like factory chimes, rear dvd, aux input, backup camera, steering audio controls, etc. Some off brand off size double din size radios might not fit properly. Using brand name radios like Kenwood, Pioneer, Alpine etc is recommended so there is not fitment issues. Compatible Vehicles: Made for Buick: No Factory External Amp Vehicles Only: 2005 2006 2007 2008 2009 Lacrosse
