Ok, so I know I hate how the stock bluetooth only comes out the right front speaker, so the question I have been trying to find for days is:

With a aftermarket HU, will the bluetooth from the HU be distributed over all the speakers in the car?

I am assuming it would be due to the bluetooth being in the headunit itself but would like to hear it from someone who has upgraded.

I'm looking at either the AVIC z130bt or the 140bh as well.

Thanks guys!

 

I have an aftermarket HU. Bluetooth plays over all of the speakers. Im using the stock speakers and stock speaker wiring.

 

Thanks projectGSX that answers my question, thread closed!
