I was just wondering the pros and cons of PAC, Peripheral, Metra brand interfaces... I have heard many bad things of each.. Any good experiences of each? Just wondering which is the best way to go??? I want to retain the factory bose speakers and Onstar..

Thanks

Joe

PAC is the best metra is junk i have had and see over 6 of these and they barley work the pac is so easy and wires nicely also steering wheel controllers are plug and play with there box

You need a PAC SWI-PS for the steering controls and an PAC OS2-BOSE for the stereo. I have done a Z-2 in my H2 and a 2006 Silverado Lt3 with these modulues.

seen a lot of bad gmos pieces. havent had any problems with the pac piece yet
