navigation issues
 

I just got a 05 A8L. I have been having problems with the navy system. After it is fully out it rapidly ticks for about 3 seconds. Very anoying. So i took it to the shop they said the limit switch is not timing out right. They said they will have to pull the unit out, and send it to audi to see if they can repair it . Or buy a new one for about $800. I will have thought that you could just reset it. Please advise on what i should do.
