2010RXVA

Hi everyone, not sure what’s started causing this but our 2010 rx started making these interference noises, even when radio is turned off. It kind of sounds like wires are burning/melting. Any idea where I should start looking first. This is our 1st Lexus so it’s all knew to me. We turned off Bluetooth thinking it was it but still does it. TIA

Can you pinpoint the location? Is it coming from all speakers or just one or some? I'm guessing it's a ground or something.

Here's my guess as to why you're always getting that interference even with the radio off. Just a guess........Even though you're turning the radio off, there's always power there for the navigation and communication (please fasten seatbelt, the bings and beeps, etc.). That's always on for obvious reasons. Try taking off the fuse for the navigation, communication, audio and see if it's gone. I believe it will be fuse number 2 in your year.

It won't solve the problem, but we can at least know for certain that it's speaker related.

Thank you, over the summer I heard it coming from the back speakers while we were driving but last few times it seems like it’s only coming from the front center speaker. Sometimes we could drive the car 1-2 hours and nothing happens and sometimes less then an hour and it happens. Some searches made me think it could be the amp causing it( moisture, water in the amp area but we haven’t had rain in long time when this started happening), or the Bluetooth part. When I tried listening to music over Bluetooth it seemed like all front speakers had the static coming out of them
