tom tom mh downloads (1 Viewer)

HAPPY NEW YEAR EVERYONE. having returned after 10 days in mid wales in the snow over christmas, and had a fabulous time in our motorhome, the only thing that could have improved our journey would have been our tom tom telling us the best routes for mh's. Definately do not want to pay £479 for a new sat nav that includes this info, so does anyone have any info on downloads for tom tom, at reasonable cost please?

You are right we live in mid Wales in a little village and as we know the area our tom tom is often saying turn around because we know where they are trying to send us is not motorhome friendly, we are the same as you we dont want to pay over £400 so if you hear of any ideas, let us know

Unfortunately mapping used by sat navs does not include comprehensive data on road widths. If planning a trip through country where roads might be narrow its worth using a printed atlas (there was a thread mentioning truckers' atlases recently) and Google mapping along with the sat nav to check first.

Graham hit the nail on the head..

NO sat nav has road widths data .. all they use for routing is the road classification, ie M, A, B, C and unclassified. From that data it works out the shortest or quickest route.. but if there are no main roads it WILL route you along the only road available, be it B, C or an unclassified road ..

Some are marketed claiming to be 'trucker' sat navs .. all they have extra are the low bridges, width and weight limits which are downloadable as POIs .. If you want these search GPS sites such as Pocket GPS World.. some are free ..

Depend solely on a sat nav in rural countryside with a large vehicle and sooner or later you WILL have problems..
