OK... so I have a few questions. I have a 2015 A4 with the MMI 3G plus and and iPhone XR. I added the AMI lightning cable and extension. The problems I have that seem to make this a useless venture are as follows. Bluetooth works great with everything, phone calls, iTunes and streaming (pandora, Amazon etc.) but you need a charging source. When my phone is connected through the AMI, it won't let you have both bluetooth and AMI connected so you have to disconnect bluetooth and therefore lose phone connectivity. It seems to prioritize the AMI over bluetooth and is a pain to disconnect via the phone. Am I doing something wrong? I can get music to play from Amazon but the AMI insists on pulling from iTunes and usually has incorrect track info while amazon music is playing.
