Hi All, Just taken ownership of an 08 A4 3.0TDI Quattro. I bought two cables for the MMI plug in the glove box. One for a USB cable and One for the ipod / Iphone. I connect a USB stick and it works a dream, however if i use the iphone cable it just says the device is not working or connected properly. I tried this with two different cables, an ipod and an iphone so it must be the MMI? I have read there are firmware updates available but at a loose end what to do. I think its a 2G High MMI: Colour screen, blootooth, 6 CD changer in the dash, Plug in the glove box, DVD Sat nav with DVD unit in the boot. Can anyone help? Thanks.
