hi can anyone tell me what the correct lead is for to connect my iPhone 6 to my cars stereo in the passenger footwell,the correct part number or are they all compatible as I don't want to buy wrong one . Skoda Fabia Monte Carlo 2012 any help will be gratefully appreciated thanks .

Not sure they do an mdi > lightning cable. I had to get a mdi > usb  cable when we got out 2015 superb but my iphone 7 is not detected for data but it charges ok.  Use Bluetooth for music in my opinion as it tends to work better

Try this part number 5N0 035 554 J

i got a usb one but it doesn't work also ,I will purchase that part number thanks for your help .
