Hello all-need some help before I take the issue to the dealer.

The mother board on my 2021 Ford Explorer Limited seems to be shot. Sometimes the radio works, sometimes it does not. The radio and navigational screen freezes up and then both do not work.

Dealer wants $200 to clear the program and try to download the fix. No guarantees that will work. If not, dealer wants almost $1,000 for new software/unit.

Any ideas to fix this major issue?

Thanks.
