It occurs to me that if multiple USB devices is not possible, then what needs to be done it to make the most of a single USB device. To that end I just ordered a wireless USB/SD interface (RAVPower File Hub) that will allow my Android phone to access stored MP3 files for music while retaining navigation and other Android auto functionality. I will report back with my results.
Do you have a Samsung phone?
