Bluetooth not working as it should in car.


Android Question

My Samsung Galaxy S3 Bluetooth fails to work as it should in my car I am told its has a different Bluetooth and that a app can resolve it, can anyone point me in the right direction please.
The 3 issues I have are:
Can not down load any numbers from the phone to the car
When a call comes in it rings on the phone and not the car system
When I make a call out for a second or two as it connects it makes a very loud noice.

What gets me my old Motorola worked 100% with the car, please can anyone help.
