I have a 2011 Mustang Prem (Sync but no Nav). I use the Bluetooth to play Pandora. When I push the Aux button it goes to Line In and then I have to switch around for it to go to Bluetooth.

Question - Is there a better work around where I can set the default of AUX to Bluetooth?

Or, I've seen the wireless USB Carplay (No, I do not have Carplay) adapters being advertised. Is there something like that for folks with older Mustang Syncs?
