If you are installing an aftermarket radio in your 2001 2002 2003 or 2004 Acura MDX this combination of harnesses are all you will need. This harness combo allows you to retain your factory amplifier, subwoofer and navigation. Your steering wheel controls can also be retained with an additional part, the AXSWC. If your MDX has a BOSE system your radio will need to have 4 RCA ports on the back label FL, FR, RR, RL,SUB if your radio does not have these outputs you will need a line out converter. This combo will result in the loss of your factory rear rear entertainment, dvd player, cd changer, onstar and factory xm radio.
The 20 Pin Blue connector in this combo is used to provide:
– Steering Wheel Control + Lead
– Primary Speakers (FL, FR, RR, RL)
-Amplifier Turn on
