I recently installed a new JVC AHD59 (Comb CD/HDRadio with Aux In) with XM PIA Mod # CNP2000UC from Audiovox. I used the GMOS-1 for steering wheel controls, and the PAC SWI-Jack for On-Star. I purchased it all from crutchfield. Now, The new head unit works flawlessly, including the steering wheel controls and the onstar, but I totally lost the automatic increase in volume upon acceleration and the rear Head unit for when playing CDs. So did I do anything wrong or not?????:confused:
