So I've been on a research bender and I need some advice Has anyone replaced the nav/jbl/ipa headunit with a CarPlay head unit successfully and retained all functionality? I know the Steering wheel, back up camera, JBL can all be solved - but I'm concerned about the park assist being retained. I don't care about Satellite radio or GPS - that's what the CarPlay is for. I've checked PAC, axxis and Maestro - and they don't seem to be a problem - but crutchfield doesn't recommend it
