Asc / Ask issues

Radio would not play so I swapped out the audio sound controller. That didn't help and I found that the only way I can navigate through the display screen is to "reboot" the fiber optic cable in the glove box. Any ideas on how to fix this would be appreciated.

Thanks

Thanks SF, I went to BMW and got the part to bypass. I tried it on all 4 units and found the Nav system was part of the problem. I left the bypass on it but still don't any any sound. Does anyone know how to bench test the ASK unit? I'm starting to wonder if I got a bad replacement unit.

There might be more than one broken unit. Voice module is very common

I failed to mention we bypassed that as well. We got two bypass units and used them on all the various units in different combinations.
