For anybody that decides to do this and has the 23 BCM installed AFTER you have already installed as 23 UC5 radio you will most likely have to do a soft reboot on the radio. I had a few things different on the radio and wondered how those changed with a BCm swap and just let it go as oh well it is what it is. Then I was talking to
@OnTheReel (thanks for putting up with all my messages

) and I was checking to see if my radio had the setting for the rear seat reminder. It didn’t and a lot of other settings were not there also. On a whim I did a soft reboot(hold power button for about 10 seconds till screen goes blank). I did that and something on the cluster looked different so I tried the maps and they worked. went back into the radio and all the missing settings were there also. My buttons on the steering wheel also work as they should.
