I am a cheap bastard and went with the Kenwood 5120 its great...the Garmin GPS is perfect, plays DVDs perfect once you ground the wire, works great as the backup camera, with the sirius receiver I can still use my factory antenna, the factory sub works, steering wheel controls work with the adapter. I went this route cause it was only like $600 and I dont need a hard drive, it has a USB cord and I can use a flash drive for music.
