Generally does the job but will frustrate you. The Bluetooth software keeps crashing even though I have up grade it on the net. The MP3 player get stuck on certain tracks so you cant use the random function. The are only two navigation settings quickest or shortest no midpoint between the two. When recently the A12 closed near my home the until could not compute a way home. The traffic updating is very annoying if you use the auto redirection setting e.g. it will tell to leave a major road via a slip road and no soon have you left it will tell you to get back on most confusing.
