I ust went through this with my '06. I think either the dash is different from'05 to '06 (can't remember for sure) and the nav radio changed from '05 to '06 (in the Ram anyways).
Mcrodney, you were quoted full boat list price, DON'T PAY IT. I have the new bezel sitting in the box right beside me in my office (waiting on me to get off my butt and do the install). Part number 1BN391Z2AB that I paid $269 (b4 tax). It pays to have friends in the parts department. I think my cost on the REC nav radio was $1400 or $1600.
