Hey guys. Just finished installing a cheap Sony Mechless head unit with bluetooth into the Aux input you get from behind the fusebox of my BF Wagon.

I've have used this just as a guide:

Its probly something simple but there is no sound for incoming calls or when i make calls. I can make calls and they can hear me but it doesnt come through the front speakers as i was expecting it too.

The radio, Bluetooth Pandora and steering wheel controls all work fine!

I didnt think i would have to tap into the front speaker wires from the new head unit if everything else seems to come though fine. I have adjusted the volumes on everything also

I'm sure someone here can point me in the right direction! cheers
