What's the best way to do this. Have already been bitten by speccing his on my new car for £500 and then finding you can get them on Amazon for £300 so being a bit more cautious now. When I picked my car up today the salesman said that I get 3 free updates so not to plug it in for a year as it's up to date now and I'd waste a free update. The website is pretty obscure and I haven't found a specific description other than the instruction to connect the Mappilot to my PC within 45 days to get free updates? Anyone now the score here?
