Does any sat nav when you ask for the shortest route give you just that? When I ask for the shortest it seems to head for the nearest main road first and is definately not the shortest.
Also how do you update the maps which I presume are on the SD card without paying a small fortune?
We have a Garmin with European maps on it. There are maps you can buy on the Garmin site but to update it does it free - well, I think it does! LOL I've never paid anyway
