I made for me simple think. I have widget on my home screen, so in one click I made all, what I need in car. It makes > Turt BT on, when conected, brigthenss 100%(screen goes off anyway, only when ringing or sms, it goes on, then max brigthenss), turn on ringing(because the bt im my car has own ringtone), turn off wifi(no needed in car). And wait, when disconected, turn on ringing, brightness to auto, turn of Bluetooth. Works fine with Samsung Note 4 and VW Sharan/Passat 2014.
