Same Problem
Sorry to say that I can not help, but I do suffer from the same problem. Mine is from an A6, and the model nav is M. I just installed it in July and it started doing this in August (I live in the US, btw). Anyway, I think it may be a faulty TMC unit (that is my hope anyway, because it is way cheaper than a new nav). I think this because the unit still works when this happens (albeit slower) and the steering wheel functions cease to work.
Ways to test this would be trying to replace the TMC with another one if you can get your hands on it, VAG the NAV so that it doesn't look for the TMC unit anymore and see if that works, or ask an Audi dealer.
Mine started rarely, but now it happens every time I turn on my car after it has been sitting a while (overnight or more). I thought I could live with it too, but it's very annoying now.
Please keep us posted, and good luck (I'll do the same if I figure anything out)
