I just wondered if anyone had gone back and had the SD Sat-Nav upgrade after purchasing the A3? I would have liked to have had it but for £495 I just couldn't justify it. I am also fairly techie and so I know that if they can offer it as an anytime upgrade then it is just a software 'update' and maps on an SD card which is a 5min job and not worth £495. Has anyone gone back to a dealer and and had this done and if so did you manage to push them down on price? Ideally I'm thinking £150!! I might be dreaming but I still reckon that is £150 profit for them.
