Just logged in to update my XXL 540 and was told it's obsolute and "could be the perfect time to upgrade!" great... and the fantastic obsolute booby price offer.... a Go 6200 for JUST £240, a 30% discount from £340. So I go and check on Amazon where I can buy it for £290 including their discount. So, a £50 saving... surely if TomTom make a product with lifetime maps obsolute, then they should replace the unit FREE OF CHARGE? Has anyone else come across this dubious offer of compensation....?
