Have a 2015 Turbo cab, can connect 2 iphones (one as phone, and one as mp3 player) as well as control ipod- no problem
2017 Macan Turbo same, different interface, but can connnect 2 iphones and ipod.

2016 Cayenne GTS- every time i connect ipod, i cant stream music with Bluetooth AUX - it tells me i need an AHA enabled phone.
so as soon as ipod connected i cannot use BLU-AUX. it disappears. have to remove ipod and then BLU-AUX comes back .

the reason for the two phones? i use the second one for streaming
and i use my primary phone as my principle contact number.

so my setup uses 2 phones thru bluetooth AUX


Any ideas?
