Axxess AX-GMLAN29 2006 Up GM Data Interface

If you do aftermarket head unit installations you know the Axxess Integrate line of products from Metra is excellent. The Data Interface for 2006 and Up GMs provides accessory power as well as retains RAP. It also retains chimes through an onboard speaker. It does include the prewired ASWC-1 harness but the ASWC-1 itself is sold separately.
