I have decided to go back to the symphony unit as even despite getting the sat nav working in my S3 I have decided I hardly use it enough to justify keeping it ! I am selling it fairly cheap as it can be tempramental at times, I think this is due to it running on a non genuine nav cd but cannot be sure I am selling this complete with the BRAND NEW Kufatec 8L plug and play harness I just bought and also the GPS Aerial. Also recently I have noticed that the sattelite reception has been poor and I think it could probably do with a new aerial. The unit is all coded up for use in a UK 2001 Audi S3 8L and comes with the security code. I am asking £140, please bear in mind the kufatec loom cost me £30 delivered literally 2 weeks ago and I had to wait for it to be sent from Germany !
