Hi all,

First off I should apologise as I don't have an X5. Did have and found this site the source for so much info. Now I've a 2002 E39 with a upgraded Mk III -> Mk IV Sat Nav. Searched this site and others and have to say that you guys rock in the Sat Nav knowledge department - hence I thought I'd ask this here.

My screen is the widescreen one that plays TV through it. I'm looking to update my maps and a friend has lent me his backup version of Navteq Professional 2008-1 Europe with speedcameras. However, when I try to install it I get the message 'Incorrect CD/DVD...'. Is this a likely to be a purely burnt backup or is it that my MK IV can't take this new version. My firmware is the v.29 (91).

Equally not sure how to tell the difference from High / Professional / Business and Premium. Any suggestions which one I am likely to have with the widescreen?

Appreciate any information you can lend to the subject.

Kind regards and thanks.
