Agree with Nos. They are all ok if ya driving a car, but with a 13'6" or 14'10" reefer on the back, you still need to consult the good old fashioned AA truckers atlas of GB. I used to have Tom Tom 3 on a Ipaq 2210, but the Ipaq died and I really cant be botherd to replace it. Iv got more hard copies of good old fashioned A-Z's than I care to mention.
However, the Disco I have just bought has got a VDO Dayton system fitted. And thats about all I know about it till I read the destructions
Right must go, late start with the truck today, got to plot me route on an A-Z!!!!
