GPS Upgrade
Can someone direct me to a step-by-step guide for installing the GPS drive on my 2003 ML350.My car is already equipped with the control module and screen as well as the hands-free telephone, cassette playerand CD changer. Is it better to source a complete control unitthat alreadyincludes the GPS drive or to just source a GPS drive to install onto my current control module?
