AVH-X3500BHS problems
 

I tried to get up with pioneer and they are not helping what so ever. I installed a new avh-x3500bhs in my frs. Everything works well but the blutooth calling. the problem I'm having is that I can hear the person i'm calling great. but, the other person is saying there is a LOUD buzzing/humming noise coming from my end, which drowns out my voice. No matter where I move the mic in my car it's still there. I tried to put my phone in the truck, and it still does the same thing, thinking it might be the radio freq. problem. Does anyone have an idea for a fix or know what's going on?

Connection issue with the mic cable? How is the cable being run? If it's not insulated and is touching a lot of other wires or metal, it could introduce hum or buzz into the signal.

so should I just wrap the entire mic wire with electrical tape?

what's should I do with the mic wire?

You could try that, or there could be an issue with the wire itself. There's no quick easy way to figure that out without buying a new mic and seeing if that works.

pioneer said it could be a grounding issue or a bad mic. they told me to go back to the installer and have them give me a new mic, but, how can I do that if I installed it myself. haha!

Now I don't know what's going on... sigh... I tried electrical taping a 8+ foot mic cord, and that's a fail. I tried a new mic, and that another fail. I narrowed down the buzzing and humming. When I'm parked or sitting still, the calls are great for the person on the other end. but, once I start driving they hear it really loud. I have absolutely no mods that add to cabin noise. anybody have any input what it could be?
