Ever since I got the Cayman I've been wanting to add a head unit to it so I can use Apple CarPlay and install a backup camera. They were always so expensive and included features I didn't really care about like built-in GPS so I never did. Since my car has the factory Bose unit, you can't just replace the head unit either. You need a HUR adapter to connect it to the fiber optic system used by Bose and those are also pricey. My car already had a Tranzit Blu Bluetooth to radio adapter installed by the previous owner so you can send bluetooth audio to the factory unit directly over the antenna cable but sometimes it randomly decides to it can't find my phone.

I eventually ran across the Alpine iLX-W650 and it's pretty much the perfect head unit for me. It supports Apple CarPlay, doesn't have extra things I don't need (hence the much lower cost), and more importantly, is only 4 inches deep leaving lots of space behind it to fit all the wiring you need to connect all the adapters you need. I got it from Crutchfield along with an Axxess AX-PO90052 Wiring Interface (HUR Adapter) and the American International POR911 Silver Dash Kit which is a perfect match with the factory panels. I also decided I'd make an attempt at getting a rearview camera working. I looked around for something that would be discrete and almost stock looking and I found this random cheap one (Natika brand) on Amazon that was nice and small and fit the bill (if you're a native English speaker, the instructions are laughable translations that make little sense). I also bought a parking brake bypass kit since you can't just fool it by grounding the wire. It needs to sense power first before it goes to ground. These are also available on Amazon and the instructions are really easy to follow.

Running the wire to the back for the camera turned out to be the easy part. I ran it by the channel where the rubber seals were for the doors, under the "umbrella holder", then back up the channels to get to where the seat belt is. I then stuffed the cable in the gap between the side compartment and the back panel to the trunk. Removing the bumper was supposed to be just a few Torx-30 bolts and a 5 minute job but the two bolts by the exhaust were not accessible to me because they're blocked by the much larger FVD muffler I have. I had to drop the muffler to get to those bolts which is a pain because the muffler barely fits through the gap. I drilled a 5/16" hole dead center above the license plate and installed the camera there. It looks like it came like that from the factory.
