After getting the vehicle back , I had to retourn for things that were missed, and not the same as when I bought it! When we mentioned that the backup assist had no grid appear on the mirror, we were promptly told it never had one???? Why would I ask about something if it wasn't there, it sure as heck had it when I bought it and they brush it off and say talk to your ( mine) insurance people, and this could go on for a 10000 more words!! Still not solved either!!
