Just thought I'd throw this out to see if anyone experienced a similar problem Yesterday afternoon backup camera worked fine. Parked in garage overnight and this morning neither the backup or cargo cameras work even when I go to 'controls' and try to manually turn them on. Yesterday was extremely hot in Montana, but don't think that should have made the difference. Truck only has 2500 miles so yes, it is under warranty, I just thought someone might have ideas. Thanks in advance.
