This is something quite interesting – a Garmin satellite navigation unit that’s integrated into the side of a rear view mirror, offered by Ford to any Ford vehicle except for the Ranger and Ka 2009. GPS instructions are displayed on the touch screen 3.5 inch display integrated into the rear view mirror. The whole system is called the MirrorNavi system and it clips onto your existing rear view mirror. It costs £299 plus local dealer fitting charges in the UK.
