Speakers will say bose on them if its bose.
Thats normal to not have a base. Thats an extra option for certain cell phones. What happens when you push the for the phone. If it says no function you dont have bluetooth to use the vehicles handsfree. Otherwise the car should have bluetooth. Youll have to check the owners manuel for exact operation.
