I have an 04 TT Coupe with the Bose Concert II headunit... The Speed Volume Control (SVC) wont shut off... I had it at the dealer, they said there was a service bulletin which completely disables the function on the radio... i had them perform that service... the SVC STILL functioned... so they told me the radio was bad. They replaced it with a new radio.... and it STILL is funtioning even when turned off.... what else can be causing this??? anyone else have the same issues... i hate the SVC function its so annoying! Any suggestions would be appreciated.
