Review on Crux Interfacing CS GMC2 Steering 2000 2013 by Kevin Vanlaere

Purchased to install a Pioneer DVD player in dash in my Suburban 05 with factory Bose premium amp. Works better than I expected. Allows me to keep steering wheel controls, doorbell and functionality or factory amp and subwoofer. An added surprise bonus is an additional 10 amp "stored auxiliary power" circuit that I will be using to control other accessories I add to my truck. The sound is crystal clear at any volume and sounds significantly better with the new head unit than with the factory Bose head unit.
