2020 PP - Is it possible to disconnect the audio?

Unplug the speaker connection/s on the back of the head unit? It's really easy to access.

 

May ask why?

 

It is ridiculously easy. Just keep in mind that after you get out the single clip and you're ready to pull, pull a little here and a little there like in the video rather than all in one place. It comes free very gracefully that way. Then just unplug what you need to unplug.

 

Any Toyota dealer OR audio shop should be able to do it for you at little to no cost.

Please consider, however, that if someone who has no knowledge of this modification gets into your car and turns the volume up near MAX. that it might blow the outputs since there will be no load for them.

 

Hang on, the speaker wires are in the same connector shells as some of the important lines.

The speaker lines can be isolated and cut easily enough. With a little more work it could be made quickly reversible if you felt the need to protect resale value.

I don't think you'll find a youtube that shows how to do only this but that one Jerry shared offers a lot of the important parts.

 

I did not know that they combined other wires with the speaker wires in the connectors. When I had mine apart, I wasn't looking into those kinds of things. Nice catch. And good point on still being able to disconnect/reconnect if you sort them out and put connectors on the ones you cut. (Last time I had a radio out with the intentions of replacing it was probably 30-35 years ago and I'm 99.9% sure the speaker wires had a dedicated connector.)

I still don't understand why it would be necessary to make it totally impossible to prevent the sound system from making sound rather than just turning the volume down to zero.

 

Ummm...?

 

don't turn it on?

 

Not on this model. If the car has the six-speaker sound system, with the 7-inch display—the default for the base model in Canada, according to the 2020 sales brochure (PDF)—it should be straightforward to disconnect the speakers at the Radio and Display Receiver Assembly, also called the head unit.

As the Electrical Wiring Diagram (more info) shows, connector I108 has only the wires to the speakers, so disconnecting it wouldn’t interfere with the rear view monitor system. This connector is the only one on the head unit with ten positions (in two rows of five) and eight wires. If it’s left disconnected, I’d suggest securing it to prevent rattling, perhaps by fastening the speaker wires to those of an adjacent connector using a nylon cable tie, fastened just tight enough to stay in place, but not so tightly that the wires might break.

Removing the speakers is another option, but they’re mounted with rivets, which would have to be drilled out.

The right front speakers are also used by the Safety Connect feature for emergency call audio. The wiring for these speakers goes from the head unit (I108) to the telematics transceiver (DCM), and then on to the speakers, and I’d imagine that Toyota’s designers would have made sure that leaving the speaker circuit unterminated at the head unit wouldn’t cause a problem.

I wondered about that, too. If it’s a matter of conscience, I’d respect that, but if it’s just a rebellious teenager, I’d suggest that anyone who can’t be trusted with the volume control also shouldn’t be trusted with the steering wheel, brake pedal, or accelerator.

 

Not even close.

Audio also comes from all kinds of system alerts.
I assume those come through the head unit.......but maybe not.

I'm taking bets on whether this is:
Just some hairbrained idea.
OR
There is an actual legitimate reason for wanting total quiet.

I sure hope we find out.

 

Fair enough if talking about ALL audio, but OP's original statement was:

"To clarify, I don't want any music to be able to be played in my car. I realize that this may mean I'll lose Bluetooth audio (for phone calls), but I'm willing to make that sacrifice."

 

The aural warnings come from other parts: the combination meter, skid control buzzer, blind spot monitor buzzer, and no. 1 and no. 2 clearance warning buzzers. (The onomatopoeia is lost in translation.)

 

I thought buzzing was kind of inherent in bee-ness, whether they are angry or not.

 

Yes I KNOW that those sounds originate in other places but they come through the head unit on their way to the speakers.........right ??

 

The warning sounds (that is, the vibrations in the air) are generated directly by the other parts I mentioned. Neither the head unit nor any of the speakers that are usually connected to it is involved.

 

ahh sam, sam, sam...

 

Piezoelectric, aren't they?

 

I was wrong
So were you
What will you do?
