I haven't yet taken this out for a drive but so far so good. It was really easy to use and surprisingly was really fast to react to requests. There is a simple and advanced mode to suit everyone and as mentioned on many of the other reviews, has so many more functions that is needed on a Sat Nav. The only downside is the map itself as this does not look as advanced as I had hoped it would be so I have reservations on how confusing it may be when trying to get on/off a highway, which lane to drive on etc.
Given that, for what you pay this is more than what I expected. I hope to continue being pleasantly surprised the more I use it.
