The bypass was working correctly. And I also double and triple checked that the mute wire was moved to the correct position in the connector. Is there a difference between European and American AVIC units? I was told by a local install shop here in Norway to just connect the parking brake wire in the AVIC harness to ground (and leave the mute wire unconnected in its original position). This seems to work perfectly without any current drain.

I'll bet you didn't disconnect the parking brake wire from the canbus adapter before you grounded it. (You ground the wire from the AVIC, not the wire from the canbus.) Done correctly, the bypass does not cause any excess drain. I never connected anything to the parking brake wire coming from the canbus adapter. The green parking brake wire coming from the AVIC was connected to the black ground wire in the harness together with the mute wire coming from the bypass position as described in this thread. Any other idea why the bypass might cause current drain?

My car does not have steering wheel controls, so I'm not able to tell. But from what I have read in this and other forums, they're supposed to work if you have the right type of adapter.

I have reasons to believe that hardware bypass mentioned in this sticky topic has a bad side effect: draining the car battery. I recently installed an AVIC-F900BT in a Volkswagen Passat 2009. I used a Connects2 CTSVW002 canbus adapter to connect the unit to the radio connector of my car. The canbus adapter provides acc power, illumination, speed signal and parking brake wires to ease the install, as well as an interface to the steering wheel control buttons. I opted for doing the hardware bypass as described in this thread. The first couple of weeks after installing the AVIC-F900BT I u

Hi, I installed a F900BT in my VW Passat 09 this weekend. The difficult part was hiding the GPS-antenna under the dash, and carefully routing the wires to the antenna, mic and USB/iPod connection under the dash to the player... Getting the USB+iPod cable to the glove box was a thight squeeze... For hooking up the player to the car, I used a wiring harness with CAN-BUS interface. I really recommend this method for a trouble-free install. The CAN-BUS interface hooks the player up to the steering wheel remote control, and provides wires for speed pulse, hand brake, reverse gear and acc power.
