Hi all; my dad has a '08 Lucerne and he wants to replace the factory head unit, it does have the amplified system and also the rear parking assist. He really doesn't care about keeping Onstar and he wants to keep the factory amplifier and speakers. He said he is very disappointed in the factory unit for such an expensive car. I suggested the Alpine CDA-9886 but in order to keep all of the chimes and warnings and rear parking assist, I am running into a road block. What about the PAC-Audio OS-4? Thanks for all the input. Oh also keep the steering wheel controls.

Edit Reason: forgot to mention steering wheel control
