I have a 1999 W210 with Bose sound. Just put in an aftermarket DUAL radio. got a wiring adapter. Bluetooth on new radio didn't work so I replaced it with a JVC. Now none of the speakers work. no pops, crackles or rattles, nothing, just dead silence. The radio is working in all modes but no sound comes out. Any ideas would be appreciated.
