The first and only time I used a TomTom was to go from Weston super Mare to Rotterdam, Holland. It got me there fine and I would definately use it again and recommend it if anyone is looking to purchase:thumbsupbest at doing what?...getting you there?
i use a tomtom in my truck and i always make my delivery.
not used a bm system,but i suspect it'll get you there too.
so then it comes down to cost and the tomtom wins hands down.
plus you can take it with you if you ever change vehicles...even take it on holiday and put it in the hire car(if you have europewide maps)
like any computer though,a satnav is only as good as the info programmed into it.get the postcode wrong and you could end up anwhere lol.
