    Navigator IV through Speakers - '12 R1200RT

    I was able to take part in the promotion to get a GPS with the purchase of my R1200RT and it was installed last weekend by the dealer at no cost. The problem I have is it I can't figure out how to make it play through the speakers. When I try to adjust the volume on the device itself it says something to the effect that it's hooked up through the audio system but I never hear anything. I've tried it on AUX, USB, FM, Satellite etc but no sound ever comes out. I've flipped through the audio system manual and the one for the GPS and I can't find where it says how it should all work. I'm sure it's something simple but I can't figure it out.

    I also took advantage of the Nav IV and bought a new 12 RT. I had the dealer install is and it does not come through the speakers as I was told it should on this forum and another. I asked the dealer and they didn't know that it should be coming through the speakers. They checked into it and advised me that they need to connect to wires that were not connected in the original install. Something about a white connector connecting to a black connector on the bike wire harness. I looked and couldn't see it. I'm going to take it in this week and have it connected. I'll advise you on the outcome and get pictures of the connection if you would like to see it.

    Nav IV & Speakers.

    I have Nav IV on a 2012 RT. I installed it. There were two plugs that had to be plugged into the bike harness. One was power to the base plate and the other was the feed to the speakers.
    I generally use the blue tooth as the feed for the GPS. And here is the trick. The speakers will only work when the Blue Tooth system is off.
    Make sure your radio is playing thru the speakers and the GPS should also play back thru the speakers. If not then the dealer did not hook up the feed to the speaker system.
    If you want to take it a step further you could look for the two connectors that should be hooked up to the GPS wiring harness. They are directly below the instrument panel; between the fork tubes on the bottom of the main frame tube.
    This view is from the right had side looking down and forward thru the opening between the fairing and the frame.

    I was looking down in there this past weekend and noticed that one of the plugs was not connected. I'd be willing to bet that's the problem.

    Me too. I think I'll stop by the dealer and let them do it. It's kind of tight in there and I don't want to mess anything up. I'll bet if I send you a pic of mine they will have the same wires not connected.

    John, this might be a dumb question, but can you tell me how you hooked your earbuds to the rear speaker?

    You use the "rear-speaker" plug in the nose of the bike and wire to a 3.5mm jack. See this BMWLT thread and/or this other BMWLT thread and/or this BMWSportTouring thread

    Nav IV with RT

    Can you confirm that this was correcting with proper wiring. I am having the same problem with a dealer installed mount; no voice prompts through the radio and poor documentation to explain it.

    Thanks,
    Marshall

    Yep it worked for me. The dealer told me there wasn't anywhere else to plug the second connector, I said keep looking. They finally got out the wiring diagram for the bike an found it. Said it was 'hidden' in the fairing somewhere. Both white connectors should be connected.

    Connectors

    For the record. They are not hidden.
    The picture I posted shows the one on the right side ( throttle side ).
    The other connector is in the exact same position on the other side of the frame ( tube) shown.
    If you need the instructions I think I still have them. I could take pictures and post them if you need them.
