Or just use a USB cable to connect the phone with the car. That's a lot cheaper than replacing the unit. It also works fine, and keeps the phone charged while you're using Android Auto. I can't see the problem, really, at all.The OEM headunits Do Not support wireless AA. You will have to upgrade your headunit to an aftermarket one that does.
My wife had her iPhone SE plugged in for four hours on a recent trip, so we could use Apple Car Play and Google Maps. When she disconnected, the battery was still at 100%. So, apparently it had enough current to maintain the charge. I haven't plugged my Samsun A10e in yet to see how Android Auto works.Unfortunately, not all USB ports provide enough current to keep a Smartphone charged. They can be data only. Like the one in my Soul. What were they thinking?
