Hello, I have some questions I'm hoping someone can help with:
My MIB1 only have FEC 00050000, which is for Bluetooth. The MIB1 has a USB and AUX port. Music media can be accessed when a device is plugged in through the USB. There is a USB option in the source for media on the car display.
When I installed MIB2, component protection was on. USB was working. It showed in the source for media (However, no sound playable with component protection on). Android Auto and mirror were also working, but again no sound because of component protection
I got the component protection removed. Bluetooth FEC was reinstated and bluetooth works again.
However, USB stopped working:
1) there is no USB option in media source anymore
2) phone still detects it's connected to 'something' and gives option to share files/media, but nothing happens on the car side.
3) when I switch back to MIB1 and remove component protection, USB works fine, but when I reinstall MIB2 and remove component protection, USB is still gone from source. Note that after I adapted the MIB2 for my car, the USB is now completely gone (even if switch back to the MIB1 and back to MIB2 with component protection on MIB2).
I understand FEC 00030000 is supposedly for AMI (USB enable). But my original MIB1 does not have a FEC for it, and therefore I don't have any FEC for this to be unlocked in MIB2.
I'm worried that even if I spend money on App/car connect, I will only to find out it won't work because USB is not detected/not working.
Can anyone tell me whether this is normal, and whether App/Car connect will in fact also add a licence for FEC 0003000 in addition to the usual android auto/mirrorlink/apple car play?
Cheers
edit:
I have a 3rd headunit, MIB2 as spare, but it's 'broken' (emergency update blue screen after a few minutes). When it's on and with component protection, I can still access USB and Android Auto.
When I swap to my MIB1, I can still use USB. But when I swap to the MIB2, USB still does not show up in source (whether or not component protection is on or removed).
The point is that it's definitely NOT the cable/port for the USB.
I have extracted the relevant diagnostic messages below:

The following event is stored in the event memory of the control module:
