You'll also have to keep the unit plugged in if you want peak performance, as the 20-channel GPS receiver seems to need the extra current. On battery power it takes an absolute age to get a decent satellite lock. Connected to a lighter socket, it has no such trouble.
The v200's biggest problem, however, is with its route-finding. If you're desperately incapable of reading a map, it will get you where you want to go – eventually. But the Destinator mapping software just doesn't seem to choose a logical route much of the time.
Here's a prime example: to get from the main road near my house to my street you can either take the first left after the roundabout, then four turnings in quick succession on narrow back streets. Or you can simply take the second left which is, in fact, my street. The v200 chooses the former, which is plain daft.
Now no GPS software is perfect but in choosing this frankly bizarre route, which takes twice as long (longer if you add give-way time to oncoming traffic), it seems to suggest that the v200 doesn't take slow right-hand turnings or junctions into account when it works out the fastest route. If it did, it would have chosen the latter route to my house. And this wasn't an isolated incident. On a trip to Wales our esteemed editor took a detour around the Midlands and ended up in a dark and threatening farmyard because he followed the instructions supplied by the v200 to the letter.
With the v200 you do get a lot for your £115. Full European maps are not to be sniffed at for this sort of price. The similar £125 Mio C220 only has maps for UK and Ireland included, though the C220 does have the advantage of a speed camera database installed out of the box (you'll have to upload a third party one with the v200).
But even with a price so reasonable the v200's average route-finding and audio instructions put it out of consideration for a decent score. If you're really on a tight budget it'll get you where you want to go - but beware, you may have to put up with some confusion along the way.
