I am curious why the shop is telling you to replace the CCC unit? After the previous 'non fixes,' not sure I would trust them with anything electronic, or opinions of same.

Also sounds to me as they do not bother to troubleshoot anything. "Update your FRM!." Always, always look for the simple answer first. How hard was it to actually look at the lock and find the broken plastic?

Did this shop do any sort of module programming or updating? Did you do any updating besides the FRM? Did this shop program the new FRM?

You need to find a local member with programing tools and skills. At the very least, find a new shop.

The AUX selection should be a simple check of the CCC programming. Not much to that, nothing external would cause that issue. If they were messing around the rear hatch, might have disturbed the camera or connection. Nobody was trying to program something in the CCC?

Best of luck.
