This is for a 2005-2009 truck and van factory OEM AM FM CD Player Radio that has been professionally remanufactured and upgraded with aux input in the face for use with 3.5 mm music devices and RCA outputs in the rear for use with a high end amplifier! This radio is interchangeable with many different part numbers. Please confirm that this is the radio your vehicle requires as some of the vehicles used more than one style of radio. The Aux Input is a snap to operate...literally! Just plug in your 3.5 mm cable and it will play in full, crisp, clean quality. When you want to listen to the radio again, simply unplug the cable! The audio is full quality and takes advantage of all sound controls on the radio. Forget those shoddy FM transmitters and listen to music the way it's supposed to sound! The RCA Outputs do not get in the way of any other radios functions and do not have to be used, though we also have this radio without the RCA outputs in our store. To use them, simply hook the outputs into your amplifier's inputs. This radio has been cleaned, upgraded, serviced as needed and thoroughly checked. Please Note: This radio will need to be unlocked upon installation in your vehicle. It can be put into a fully functioning test mode for 10 minutes at a time but will need to be taken to a dealer for permanent pairing. This generally costs around $50 but will sometimes be done for free if you have a relationship with the dealer as it is a 5 minute process. Please make arrangements before purchase.
