The Garmin Nuvi 660FM features a 4.3" widescreen touchscreen display, pre loaded maps of Europe, Bluetooth hands-free calling, integrated FM traffic receiver for avoiding traffic jams and a range of entertainment tools including MP3/audio book playback. It's sleek, slim design means it will also fit comfortably in your pocket!
Having identified all the features I wanted in a Sat Nav [Widescreen, European Maps, Spoken Street Names, Traffic Alerts, Safety Camera locations and FM transmitter to listen through car stereo], I identified the Garmin 660FM as the one for me. Few places seem to stock the 600 series and those that do mainly seem to be offering refurb or white box items. These are little cheaper than this offer from Comet and you can get 2% back through Rpoints as well, for using reserve and collect.
