I bought the maps for a Go and use it on the Dimaond. Works good. However the version for the Diamond is half of the size, and with just 4GB internal memory this is a issue to change to the official maps for the Diamond. I just don't want to spend antoher 59 Euro for that. Do you think TomTom would exchange the maps if I write an e-mail to them?
Does anybody know why there is such a huge difference in memory for these maps. Go=1.6GB, TT7 = 800mb
