I’ve been trying to get my Ipod to work without taking up the only phone slot. I looked at the users manual and in one place it states the usb ports are for charging and no data port is in the XT6. In another place in the manual it states there are data ports. Right now I have the Ipod paired using bluetooth and can listen to music. However, I can’t have my phone on at the same time. I just got an adapter for regular usb to type c. Maybe the type c port is a data port. I’ll let you know if it works. If you don’t know the difference between the two types of ports a nondata port only charges a device, a data port charges and reads the device to be played through the cars system. If I moved my music to my phone that might also work.
