Is this part necessary if you add an aftermarket head unit and you have the Boston Acoustics stereo? I have the factory 6 disk cd changer in dash and I am upgrading to an aftermarket navigation. I would prefer to either retain the factory amplifier or use the 50x4 built into the new head unit.
Any advice from those of you who have already made a stereo swap?
Also if you are using this have you had issues with your sunroof? I read on a charger forum some people were having problems with the sunroof when using the PAC part.
