Actually, now that you mention it, that is one thing about my Jeep that is actually a little broken. The USB port inside the center console will work with AA but randomly drop out. I have since only used the one in the dash since week 1. I have a 19 tho.I recall reading somewhere that there were some issues with some 2018 and not having a USB port that was capable of running at proper speeds. Maybe that is what is going on with mine. I have it working fine about 2/3rds of the time, but it never fails that when I really need it, it fails.
