Thanks for helping on this. Ive started looking at a few places on the web

I got mine off ebay around 2 and a half years ago. It came from EUROPE, it wasnt brand new but it looked like it was and came with latest maps at the time and a GPS antenna.
 
No I haven't, do you know where to download from, or even how to check which version is installed?

It's a seat version

I think that is your problem, basically when you normally enter the post code under city/postcode input field it allows you to type in the whole postcode now.

Not sure if the SEAT version allows this due to the lack of firmware updates for this unit. Could be wrong.
