I am only getting Sirius stations on my MMI and can choose any of those stations and listen to my radio just fine. However, I am no longer able to see any AM or FM radio selections on the MMI screen. Only the Sirius option appears. For some reason, the AM and FM stations have disappeared. Just before they disappeared, I had a message stating: Updating Stations. That message has appeared before and after a short while, the new stations for the area I am driving in appear. I have good volume and the MMI screen has all the information about the stations and artists when listening to a Sirius station. I have reset the MMI but it did not help. I saw no problem with a fuse. Any suggestions for this A8 2005?
