Ford dealers are now offering a rear view mirror option for its cars which incorporates satellite navigation.

Replacing the original rear view mirror, "MirrorNavi" means drivers can see the navigation at the same time as checking the rear view. It is compatible with Ford car and commercial vehicle ranges and can be fitted in an hour by a Ford dealer and is mounted without any visible wires or damage to the main instrument panel.

The "MirrorNavi" is made by Garmin and Wollnikom and has tinted and dimming mirror glass, battery charging connection and anti-theft security and costs £299 plus local dealer fitting charges.
