Thanks, this looks really promising...it says the Xanavi X7 covers 350Z '05 - '09 but it says "Please double check your previous disc to ensure this is the correct product for your system. The Xanavi X6.0 and X7.0 are separate systems."
My previous disc doesn't have any reference to Xanavi but NAVTEQ, do you know if I'm likely to have any issues with compatibility or it being a different program?
Really don't know, best to give them a bell or an email to check.
