Hi all, I have a '14 limited with sync and navigation. Does anyone have first hand experience with installation? I'm debating getting a pioneer AVIC-W8500NEX. I see I'll need a idatalink maestro to keep the steering wheel functions. Will I be able to keep the rear controls? Crutchfield sells a kit (PAC C2R-FRD1) that allows retention of rear controls, but can that be used with the maestro if needed? What will I need to do to bypass the parking brake block? Thanks for any help.
