I'd make sure that direct line aux input is an option in any car. I switched to that primarily for this reason.
Very true....I hate that using bluetooth breaks voice input. My research has shown this was fixed in the Google OS update...but no telling when Samsung and the carriers will push that out.
I think the mono feed was coming because I had under accessibility mono audio for single earpieces. I bet this setting still applied hooking up to the car. I decided against buying a car anyways.
