Bluetooth

[vishnus]

Dear All,

I would like to know which Bluetooth car kit is better in all contexts.

1) Hands free bluetooth car kit or

2) Factory or dealer installed bluetooth car kit .

As you all might know the price for both is a huge difference since the first one is plug and use the second one requires a module and switch but will display on the car oem head unit the name and number of the person we are calling. I have prices for both of them . Please advice.
