I bought the navman 1400 satellite navigation system with smartpath 2 software and an acer n10 pda. Gps is very slow, takes about 2 to 3 min average to get first fix. Does now work well sometimes inside cars. May take upto 10 min if cloudy. Smartpath 2 maps are 4 to 5 years old and outdated, it some times navigates through streets which are dead ends. Instrusts you to turn left after you leave the roundabout. Gps is acurate to 10 metres.
