Hello All

I've recently purchased a Yatour virtual CD changer device
I connected it to the Concert head unit and it worked correctly on my 2011 A3 with Concert headunit.
However, I seem to be stuck with the choice of just 6 CD folders on the headunit despite putting 22 albums on the SD card for the Yatour unit.
Is there any way to make the headunit recognise more than 6 CD's, or is my only alternative to create 6 virtual 'CD's' on the SD card and put 99 tracks in each folder ???
Thanks for and help, guidance or assistance
