Navman S100 GPS unit


Entry-level GPS in Navman's S-Series Platinum provides excellent value for money

Design, user interface, large display, keyword search method, text-to-speech pronunciation, clear map screen

Touch-sensitive keys aren't always responsive, glide interface can be annoying to use while driving, traffic channel antenna optional extra

The Navman S100 GPS unit does lack many advanced features, like Bluetooth, FM transmission and built-in traffic capabilities, but it still provides an excellent navigational experience on the whole. This device is excellent value for money.

Satnav head-to-head: Navman S100 vs TomTom Go 540 Live


For those who are regularly behind the wheel, this is an excellent, feature-rich satnav.

Going purely on features, the TomTom Go 540 Live knocks the Navman S100 into a cocked hat. Sure, it’s more expensive and if you sign up to the Live updates you’ll be paying almost £100 a year, but given the vast chasm between the two in terms of...
