Just done it ! You guys are nothing short of awesome, so a big Thank You for helping me out

The DVD-R worked first time. Took about 60secs to install the SW, and a further 3 mins for me to realise that I needed to put the original DVD back in to get the maps up ! Thanks for telling me about the 8 sec Service menu, which I wouldn't have known about otherwise. My 2004 X3 now looks like it could have come out of the factory last year instead, sat nav graphics wise at least !

To celebrate I even paired my wife's new mobile phone with it - something else I'd been meaning to get round to for ages since she upgraded handsets in Sept !!

cheers again
Tony
