The garmin i3 uses the simple scroll wheel in the centre, scroll it up and down and push it in to select things, very simple unit and fantastic for the money.



This is mine, driving NE along the coast road in barrow, my next turn is 8.8 miles away, the unit will count down the distance then when 500ft away it will zoom into the turn to make it easier to see. Mine got my from manchester to barrow-in-furness 2 weeks ago, then back again! took me just over 4 hours and it was spot on with its estimated arrival time.
