The S150 is Navman’s mid-range offering in its Platinum S-Series. It features a fully touchscreen-driven interface on a 4.3-inch display screen, Bluetooth, spoken street names and lane guidance on motorways.
Pros: The S150’s screen mount was excellent; both secure on the windscreen and easy to remove. Searches were quick and GPS lock-on was generally very good. The map layout uses a sliding tab that moves in from the left, giving the road map maximum screen space at all times.
Cons: The touchscreen interface uses a sliding finger metaphor (similar to the iPhone or iPod Touch) which can be tricky to operate when the car is in motion – even for a co-navigator.
Verdict: A good price for the features on offer, but fiddly touchscreen is this GPS’s weak point.
