Can anyone give feedback on how good this is - quality of info, ability to use full postcodes etc - assume very small screen?

i have not got one myself but from other sites they can not fault it and no issues with it so far from other members

yeh feedback has always been good buddy

Fitted in my car. Not had any real distance journeys so far but I like it as it's fast to update, easy to input destinations via address or co-ords, and the screen is clear and light adjustable through the normal dash lighting rotary dial.

The female voice used is pleasant, and while speaking nicely cuts out the other sounds being played.

Screen size is fine, more than adequate for its purpose. There is a zoom facility built in so you can alter how much of the map you see while using it.

Unless you use alot in my opinion waste of £400 option

Unlike the Molten Orange option.

If you paid for it yep which I did NOT
