I’m stumbling with infotainment system issue and hopefully someone could help. So when I got the car it had issue that the infotainment system (discover media) didn’t remember language, Bluetooth and sound settings. Dealer checked from their system that it was issue with earlier software version and update was available. Ok, took it to dealer for them to update it but they tried in two different sessions and said that the update fails when around 80% ready and they couldn’t do anything about it. Choices were basically to change the infotainment controller inside the glove box. However it is very expensive so it was not an option for me.
I found out that Zenec makes VW specific media players (Z-E1010) so I decided to buy that from the fraction of OE unit price. It was said to support the OE functions and work with the CAN bus. So I got that Zenec infotainment system and installed it. It seems to work nicely and it uses the CAN to communicate with the car. However I lost the forward facing camera so lane assist and automatic head beam are not working anymore and I got permanent DTC “U112100 - Databus missing message”. Contacted Zenec and they said this is because this system is not supporting lane assist and traffic sign recognition and there was clausal about it in the Can bus overview document saying: “No integration of camera-based electronic assistance systems such as Traffic Sign Recognition and Lane Assist”. Ok, I thought that it is not integrated with the infotainment system but didn’t know that it stops completely working, as it wasn’t interacting with the OE infotainment system either.
This is showstopper to me as I don’t want to be missing any vital safety systems in my car. However when I disconnected the OE unit from the glove box I was wondering why was there this dual fiber optic connector left unconnected. I studied it to be the MOST bus connector. I also found out that there are MOST bus jumper leads available which are advertized to bridge the fiber optic cable of defective units. So I was wondering that could the forward facing camera be connected into this MOST bus and now that the signal is not passing through it is not working. By adding this kind of jumper could it be possible that the camera would work again? At least the fiber optic is not between the display and central unit so something else is using it.
Sorry for the long post. Thank you in advance for help.
