If you havent got the patience or brains to get on with Basecamp (I for one have neither and still use the dinosaur that is Mapsource) then have a try of this.

Had a go at Tyre as recommended by Simmo and a few others and not reallly impressed.
myrouteapp I have just tried and seems decent enough so far although havent done too much with it yet. At least I can use it on my tablet unlike Basecamp and Mapsource.
Give it a go and see what you think. Worth a try.
