My wife's old iPhone 6 connects with her new 2014 Subaru Forester Harman-Kardon system before she even opens the door (literally). My Samsung (and older HTC) phones won't connect with my Kenwood Excelon KDC-X798 system until I'm halfway down the street. And then each time I get out of the car and it reconnects, I have to push PLAY a couple times to get it to start playing again. Hers picks up at the exact point she turned off the ignition and restarts seamlessly. Ideas? I've made sure I have the latest BT driver on the phone(s), the head unit might be an older version.
