My new head unit connects to my phone with a USB cable to use Android Auto. Unfortunately there is very little power coming through that USB port, so I have to unplug it from the head unit and plug it into the cigarette lighter if I want to charge it, meaning I can't use Android Auto.
Is there an off the shelf cable that will plug into my phone and simultaneously get power from the cigarette lighter and feed data to/from the head unit?
I've seen a couple of things that might suit, but don't want to risk damaging anything if power goes somewhere it shouldn't because I got the wrong cable. Can anyone post a link? Thanks in advance.

Can't you connect the phone thru bluetooth?

Maybe you need a y adapter cable a fag lighter 5v adapter. The power situation might be OK, but you could end up with ground loops.

I can connect audio using Bluetooth but that doesn't work for Android Auto.

That's the kind of thing I was thinking, but want to make sure I get the right thing.
