One of the last devices made by United Kingdom-based Evesham Technologies -- before it went out of business in 2008 -- was the dash-mounted Nav-Cam 7700 GPS navigation system. The device also plays MP3s and allows you to view pictures in its pocket-sized display mount. To update all Nav-Cam models, contact another company, Tewktech. This is often needed to unlock new functions and to keep maps updated with current information.
