No Bluetooth, aux or phone

rod.bearings · 07-10-2020, 07:17 PM

All music, idrive cic and tones work. But for some reason the Bluetooth keeps saying "please wait"

MOST connections all have a red light. Combox/tcu has power going into it. When I try unplugging it all sound turns off (so I think the combox is working). Fuses all look good.

Got a coder to try and code the combox but no communication.

Any ideas? Gonna try someones working combox and will report back

Yes I still have the red light. I'm beginning to think it's the combox

remove MOST plug
remove 26-pin power plug
insert 26-pin power plug
do module itself emit red light ?
