Firstly, apologies for another "thicko" question. I did a spec check (previously) on the A3 (2013) that I bought yesterday, I was told one of the options it has is USB / Ipod connect - so where is the USB port ? The reason I'm interested is that I'm having real problems with the AMI cable I bought from Audi yesterday. It's got a white collar (part no. P A4F0 051 510 AC) they told me that it's what they sell for the iphone 6. I was expecting a green or yellow collar but they told me the white one had superseded both and it was definitely the correct one for the iphone 6. However it just keeps connecting and reconnecting every 3-4 seconds, so if the USB option is another way of connecting to the AMI (?) I'd be interested in knowing. I might have got the wrong end of the stick completely, however ? Thanks !
