I'm not overly impressed with the radio and was considering purchasing a replacement through crutchfield.com.
They have a number of units that will fit, but there are two installation solutions for the vehicle: 1) use a Crutchfield kit (free with most stereos) that replaces the factory pocket in the dash; or 2) purchase an adapter that replaces the factory radio/climate control panel entirely. - Metra OEM Adapter $149.99.

If anyone has replaced their radio I would appreciate hearing about your experience. The Adapter would work but takes the automatic capability away from the heating/cooling system.
Thanks
