easy to use and excellent value for money

still haven't worked out how to update it

Nice size, shape, design, graphics and touchscreen. Easy to use without even reading the instructions. Easily connects to PC for map and voice updates.

Charges only via USB or car cigar lighter as there's no wall charger included. Can't use it while it's plugged in to the USB.

IT HAS A VERY CLEAR SCREEN AND IS EASY TO USE .

SOMETIMES WHEN YOU TAP THE SCREEN THE UNIT DOESN'T RESPOND .

Fairly quiet directions voice, but otherwise cannot fault it :)

Generally very satisfied with all aspects of the product. A lot better than I anticipated.

None really, but you must be prepared to access the manuals on your PC and install the software supplied with the product.

Good size, easy to see, nice and clear. Good value.

Volume isn't loud enough, even at full volume defineitly needs to be louder but apart from that good buy.

wide screen easy to navigate

volume not louder enough

Accurate, easy to find route.

Directions very quiet.
