Over the past week, I’ve had three people tell me that they’re hearing a horrendous buzzing sound when I talk to the over the Bluetooth connection on my 2012 Honda CR-V. This after six months of flawless performance. Perplexed, I investigated.
Sure enough, even though the sound is crystal clear on my end, there’s a horrible buzzing sound on the other end. It’s almost like someone is running a band saw in the background, making it very difficult for them to converse.
I’ve checked for possible sources of electrical interference (e.g., from my after-market Garmin GPS unit) but I haven’t been able to find an explanation. Since we also have a 2012 Honda Odyssey with a Bluetooth connection, I’ve been able to rule out my phone as the source of the problem — it really is unique to the CR-V.
Update: I’m please to report that the buzzing problem has been solved. They (finally) replaced the microphone and that took care of it.
For the record, this is with an iPhone 4S (same deal with my wife’s iPhone in my car), though I’ve now read about people having similar problems with Android phones so it doesn’t seem to be specific to a certain model of phone.
After a bit of Googling the most likely culprit appears to be the Bluetooth microphone. I’ll have to take it in to be diagnose to be 100% sure but until they can show me that something else is to blame, that’s my working hypothesis.
If you’ve been having problems with a noisy Bluetooth connection, please share details in the comments section, below.
