I have a Nokia N73 at present. Thinking of N95,96,97 or 5800
Using tomtom, garmin and sygic (all Latest). Problem is they run really really slow lagging is an understatement.
Often still at a roundabout when i left 90 seconds ago...
As a Nokia user and then WINCE user (HTC) I find the Iphone to be much better to be honest and its the only phone I have ever had that allowed good connection to bluetooth hands free in my car...
