I'd be very wary of buying a satnav from a manufacturer you've never heard of. Stick to the major brands, Tomtom, Garmin, Mio etc etc. We evaluated a number of these and declined to sell them. The units themselves are ok, made by the gazillion in China but it's the software that lets them down. It's most unlikely you'll ever find a map update for them. It's very unlikely you'll be able to get another sat nav software to run on it. I know, we tried!
