Hi,what do you mean by after setting its keeps getting lost?As long as the disc works then its the correct disc for the car otherwise it wouldn't work.However bear in mind that the disc(2002 version)is now 9 years out of date and there have been a lot of changes to roads and their layout since then,so you really do need a more recent/updated disc,hope this helps.
Thanks for the reply, regarding the SATNAV going of course, it will start out fine then anything from 2 miles it will go completely off course saying that I am in a completely different town that could be 30 miles away, would just updating the disc solve this problem?
Hi,it might solve the wondering off course although I am not entirely sure,reason being that when you input an address into the system it usually shows several up options with the same street name but in different locations/towns - question is are you chosing the right one?I had a 2002 disc in mine which I updated last year to a 2009/10 version,however did not experience your problem.
