Just as the title says, upgraded the factory radio from the Uconnect to the 4200, also used the Idatalink Maestro RR with the CEH harness, and the RAM USB to retain the factory parking sensors, backup camera, and the center console usb/aux. I did lose Sirius and the chime for the backup camera, but I didn't want to pay extra for those pieces as I don't use them. Everything was pretty much plug and play, flashing the Maestro was probably the most frustrating thing, as it didn't like my Windows 10 PC and google chrome web browser but there are work arounds. Overall the install took a couple of hours to get everything soldered and wired correctly. Everything works as expected. Subs and upgraded speakers soon to come.
