Hi, you clever lot! Please can you help. I have a 2006-607 already loaded with the Britain Sat Nav cd, I've never removed it. I am going to france and i have the french navteq pack 2005-6 edition in the glove box. It has 4 discs in the pack #1 looks like the map jobby / #2 is 5.5D disc / #3 is 6.6D and #4 is audio and telematics. Am I to assume that I already have the 2/3/4 discs already in the car but just need to replace the GB disc with the french disc??????????? help doh!!!
