Aftermarket HU in Mercedes-Benz E320 - CAN bus?
Hello, I am trying to add an aftermarket head unit to a 2002
Mercedes-Benz E320. I would like to keep the Bose amp and speakers and only replace the headunit. I have the necessary Metra wiring harness (#70-1784), but I am not sure which way to connect the wires. Using a multimeter to check the wiring harness, I can only find 12V power and ground. Are the other control wires handled by the CAN bus? Is it possible to add an aftermarket head unit to a CAN bus system? I've heard a steering wheel adapter would give me the control lines, but I don't need that function or that expense. Any other way? And does anyone know the pinouts of the 2002 E320? They are apparently not the same as the SLK, though they both use the same head unit. Any help would be appreciated. Thanks. |
