Can somebody tell me where to start to change my current basic CD player to the mmi 3g high system. I know a couple of people have posted threads regarding their mmi upgrade but I don't think anyone has started from a setup which is as basic as mine. I have the smaller red screen in the dash so I appreciate I will need to change the trim and screen. Then I only have a single CD player so I guess I will need a different type of glove box to take additional equipment? Once I have an idea of the hardware I will also need all the leads... Any help here would be much appreciated.
