Hi Ameetw,
Wyrrej must have it right because I have had no luck with the TV tuner. Also the sat nav shows a picture of Japan (at least I think it is) the guys who repaired my unit said that the new Clarion sat nav system could be adapted for it but at a cost. So in view of the traffic situation here in the U.K. (gridlock at certain times) I decided to buy a Trafficmaster and a top of the range radar detector which worked out cheaper and besides I just use a printout from the Microsoft Autoroute.
