I did, and I got the typical outcome for dongles. Left it plugged into my car aux until my wife wanted to play music off her iPhone 6... turns out it can't use that dongle. She disconnected it, then it got lost beneath the seat eventually. Had another for my headphones, turns out it can't use the wired mic so it's kinda useless. Third one broke. Other car has Bluetooth, but it sucks, often doesn't auto pair or the phones fight over it.
This is a bad compromise that didn't need to happen; I should just be able to plug headphones into my phone. In the end, I took my old iPhone 5 and left it in the car for playing music. It's the better phone.
