Conversation Between nzelinsky and twostepbehind

About grounding the wire for trip meter. Did you already install the deck? there are three wires for the steering wheel control the one for trip meter ground is brown and white I believe. Its a little tricky to ground, what looks like a good ground is not, you will have to ground it farther underneath the hu. The wire is with the rest of the wires for the stereo behind the centre console

Hey you made a post in the Bose thread about your trip meter not working after the new HU was installed and someone said that you need to ground a wire to make it work. Did this work for you if so where is the wire located? Thanks
