Honda CR-V Bluetooth Buzzing – Problem Solved!

by Michael on May 1, 2013 · 10 comments

Remember when I was having trouble with a horrible buzzing sound on the other end of calls from our 2012 Honda CR-V? We got it fixed. And it wasn’t a software glitch, electronic interference, or anything else they tried to blame.

After a couple of trips to the dealer to have it checked out, and after telling them that the solution was almost certainly to replace the Bluetooth microphone… They finally listened and replaced the microphone.

And guess what? That instantly solved the problem. This was back in early November, a week or after my initial post. I just didn’t get around to posting an update until now. Best of all, the problem hasn’t recurred.

Another interesting tidbit: When they finally agreed to replace the microphone, it was on backorder. This suggests to me that this is (or at least was) a fairly widespread problem and that they’ve had to replace a lot of these microphones.

It’s also worth noting that, just as I was walking out the door after having the microphone replaced, another guy was coming with the same complaint. The Bluetooth connection in his CR-V sounded great on his end, but there was an awful buzzing sound on the other end…

If you’re having a similar problem then I’d highly recommend pushing the service guys for a microphone replacement. With any luck, they’ll agree to do it and your problems will soon be a thing of the past.

Now if I could just get the new Google Now app to stop hijacking the Bluetooth connection… A guy can dream, right?

Yeah – we’ve had the same issue for a while now. Is your still working?

This is a known mic problem by Honda which have issued a service bulletin replacing the mic and moving it to a new location.

Before you replace the mic, check the connector. The connector used is designed for quick installation on the wire harness. The unstripped wire is layed into the contact barbs and the molded door is snapped over forcing the wire into the barbs cutting thru the jacket and making electrical connection. Remove the connector and press that door firmly, clean the contacts and reassemble. Give it a test, worked for me!

Update, remove the connector from the mic only and press. Removing the connector from the wires may be interesting.

Hey Vic, been having this problem for a long time with 2012 Honda CR-V, took to dealer and of course it worked fine. The problem is not consistent, would check your solution but don’t know where the mic is located or the harness you are referring to. Can you give me some details on how to do this? Your assistance will be very much appreciated.

Since this is Honda’s problem, why my dealer want to charge me $268 to replace the microphone unit? I got my car in 2012 and this problem always there.

This noisy Bluetooth problem is a one way problem. Th person making the call hears no noise. Sounds perfect. However the person receiving the call hears a lot of garbling background noise. The Dealer has replaced the mic but the noise is still there. Anyone have any other ideas?

I flipped the switch next to the microphone. that instantly fixed the problem.

hi Brian,
Can you be more specific on “the switch next to the microphone”? I don’t see anything on the dash board that is a switch?

I flipped the switch next to the microphone that says “Off” & “Door”.
After switching it to “Door” the high-pitched noise to callers went away.
