Hi, I just wondered if anyone knew whether there was an output for a subwoofer on the back of my head unit. I have the 3 series e46 convertible with what I think is the standard sat nav, T.V head unit in

Cheers

I took mine e46 to a place called audio island (which has no gone bust) he told me it's possible but it's a ball ache and not reliable.. And told me it's been a ba@tard and not worth the hastle

Google Cartronix they can upgrade your BM54 Radio unit for you, they have a good reputation

Try dynavin store they have got a nice updated unit with so many cool features on it and is a perfect factory

Finish look, money well spent and add value to the car
