3 weeks ago I went to my dealer for USB/Ipod retrofit (it's not 6FL) but does the same thing with the connector in the glove box instead of armrest.
They installed by mistake the classic Ipod retrofit (no USB). My car goes back tomorrow for replacing the misinstalled interface with the USB/Ipod one.
The dealer installed USB/Ipod give the same possibility as classic Ipod interface but with the possibility to add USB stick / drives on top.
I have used the classic Ipod retrofit for 3weeks now and as from tomorrow I will get the USB one, so I will let you know my findings by end of this week. (first impression by tomorrow)
BTW, I'm from Belgium in Europe and as per my dealer feedback the USB/Ipod retrofit is available to any car in Europe regardless of Idrive / non-Idrive / business radio / non business etc... I will ask confirmation by tomorrow.
But I know US and European car gets very different hifi installation, that could explain the option is available in Europe only ??
