Gti: I was told that there were no firmware updates for the MDI, and yet you have updated yours. Care to share what is involved? How do I determine the firmware level of my MDI ('14, JSW, TDI, MT6, with RNS-510J, firmware 5238 or something like that)? I have a Vagcom, and some knowledge of how to use it.
I'm chasing an intermittent condition where I must (from time to time) unplug my (admittedly older) iPod, and re-plug it to get the MDI to play the iPod. When it fails all I see when is the word "Aux" on the RNS-510 display.
Note that both iPods (I have two, of different but older vintages) are current on their firmware, according to iTunes.
