Allthough you can copy the cd/dvd it is very unlikely you could add any data to it from another source.
New updated cd/dvd's usually retail at approx £150, you can sometimes find them on Ebay.

 Thanks for the reply OM - appreciated.

 Is it possible to just copy the owned original DVD for the Sat Nav and then just add the Point-of-Interest (ie Speed Cameras) to the data info on the DVD you have just made -- and then use that DVD for updating the Sat Nav unit ??

   If you have a cd or dvd based system you have to purchase the updated disk - usually for loads of dosh!
   The TomTom, as most of these aftermarket units, works off of memory and was designed to be updatable.

     Hello there,

     Does anyone know how to update the Database contained in the built in Sat Nav systems in the XK8??  

     Having owned a TomTom system, where it is possible to download and add an excellent UK/Europe Speed Camera Database to it (www.pocketgpsworld.com) , can one do the same via the Jaguar Data DVD with the POI (Points of Interest = Speed Cameras) added to that ??

     Thanks,
