USB + SD + AUX adaptor for Audi Concert 1/2 Chorus 2 Symphony 1/2 Navigation MFD Plus (RNS-D)

Easy to make it work, a nightmare to fit as the cable from cd player to adaptor is not detachable. Initially I thought it doesn't work as it doesn't read cd 2 3 and 6, tried with two different micro sd cards so I think the card reader is no good. Used my adaptors from micro sd to SD, those didn't work at all, again two different ones. Last solution was a SD card that I found in an old camera which seems to work at the moment after wasting a whole day using different ways. Also what it doesn't say in the description is you can only make 6 folders equivalent to a disc changer, each folder with 99 songs. If you put more than that it won't read the folder at all. And one last thing if you use aux you need to take the card / stick out and when you go back to card it takes ages to read the card. Edit: After adding some more music on, it will only read cd 4 5 and 6. Not impressed with the product at all and the card adaptor seems like one of those 50p ones that you buy from some dodgy website.
