I bought one of these as my first satnav for my first car. Ive used my dads garmin c510 loads before i got this and i loved it, i genuinely felt confident just going out anywhere with the garmin it never fails to impress. The navman s50 is packed with features some of which arn't that great, the phone function requires you to reconnect and pair a device everytime you want to use it which takes a long time, i thought it would be more just have the bluetooth on your phone turned on and off it went but i was wrong. You end up not using it because its too much hassle to set up. I think they have tried to make this device too complicated, the user interface is ok but not great, sometimes quite complicated to find poi's near where you are. Also the touchscreen is not great, sometimes you press it and its fine but other times it registers the press and does nothing, sometimes the interface seems very slow. Its also just got me lost too many times, ive only had it a few days and its tried to take me down two dead ends and if your making lots of turns in inner city driving the screen takes a while to update. also the voice commands for a turn are very late. The best thing i can say about this satnav is the thing that attaches it to the windscreen very solid design!
