My 2021 no longer connects automatically either. I just got it back after 2 weeks at dealer for faulty APIM module which was making screen go dark -- and the battery needed replacement. Not impressed with electronics so far.
Whenever I start my truck, there is a whirring noise coming from the back seat area. I think it’s coming from the pro power unit but not sure. It seems that the pro power unit is always turned on by default. Not generator mode. Just the standard mode. Any thoughts?
