Speed-trap hunting is key to the Proline; updates are free for six months, then cost £59.40 a year. The unit is near identical to the S600 (Page 108), but adds TMC with a standard aerial and an MP3 player. Main gripes are the limited POIs and hefty price – a shame, as it has a comprehensive yet easy-to-use interface, clear display and great 3D pictograms.
