My brother paired his phone with my bluetooth while my phone was connected. Just has to set his as primary temporarily and he could play through bluetooth audio source fine. That's the best solution. It's not as easy as an aux port, but Ford decided most people are moving away from AUX ports by now in favor of using USB or bluetooth. Apple is the one with the weird connector. Androids only use one of two connectors, USB micro or USB 3.0 micro.
