Smokey, you are in the Oz... there is a company that makes MimicX2 somewhere in Australia, their product takes touchscreen overlay and makes it work on the cars and cellphones... like in my setup, plus the overlay on top of factory screen, and then you have it... however, there were some sales and delivery issues with guy who sells it... it was a couple years ago, if he is still in business he may have resolved the issues. Have you heard of it?
PS. The MB was my wife's... while everyone around was impressed by the looks of the car, she wasn't thrilled... so, she got herself a 2012 335 M-packet... lol... black...
