Items that did not work.
Steering wheel controls. Source worked but the volume buttons just fwd to the next song.
Navigation looked good but no connection for the GPS antenna so it thought I was next to Central Park NY.
Apple Car Play. Could not get this to work. It just keep flashing a accept screen on my phone every 10 sec or so and would not connect.
Logged radio int WIFI but keep getting “download failed” message.
Backup camera did not work.
The plastic trim peice has a different radius in the corners.
The speed of the new radio is considerably better than the 2017. The items that would need to be fixed prior to changing to the 2018 would be the backup camera, apple car play and steering wheel controls. Adding a GPS antenna should be simple.
Does anyone have access to year specific wire diagrams? I have searched with no luck. If I could get a copy of the 2017 and the 2018 I could see what the differences are to see if it is reasonable to modify to get the features working.

Thanks for giving it a go. Between the unknown compatibility and exorbitant cost, I decided to install a Pioneer AA/CarPlay head unit with Maestro RR in my 17 BRZ.
Regarding CarPlay not working... this may not be an issue with using the 2018 head unit in a 2017 BRZ.
CarPlay/Android Auto can be VERY picky about the USB cable that you use. Try the OEM usb cable (one that is fairly new and has not been sharply bent, stepped on, etc.) or as short as possible of a HIGH quality aftermarket cable and see if anything changes.
There are a lot of threads complaining about issues with the factory AA/CarPlay head units in Subarus beginning back when they first appeared in the Impreza and apparently they are still pretty buggy for a lot of people to this day. Make sure that the HU and iPhone are both using the latest firmware.
Regarding the BU camera not working... does it switch to a black screen on reverse or just do nothing at all? That might help narrow down what kind of issue is occurring.
