My main button on my mmi unit is broke , I have pulled it out & looked behind & the wires connecting the button to the unit are snapped , making my sat nav useless . I have heard that Audi can't repair this problem but will raplace the whole unit for a small fortune , I have looked on eBay for a replacement unit , does anyone know if I was to purchase one of thease can it just be installed or does it have to be programmed to my car , I once tried my sd sat nav card in a friends car who has the same model but the sat nav did not work so I'm wondering if I would have a problem using the sat nav sd card in a new replacement mmi unit ? Does anyone have any experience with this ?
