2015 HL Limited. When I call my Wife from a land line or cell phone my voice echos back to me on a 3 or 4 second delay. This only occurs when her phone is connected to the HL Bluetooth. This has happened on multiple Iphones. She does not have Entune on her phone, has anyone seen this before? I will go the forget phone, re-pair route but am I missing something in the settings? She does not hear anything being repeated.

I noticed this recently with my wife's phone too... same HL vintage. FWIW I've only noticed it since she got an iPhone 7. It wasn't a problem with her 6+.

Is the phone volume in the car set super high or something? The in-car mic might be picking up on your voice through the speakers.


I notice that my wife's replies are after the echo indicating to me that the unit isn't doing basic noise canceling of sound that the speakers emit.

I'm now wondering if by any chance DriverSpeak is enabled - and the head unit doesn't know how to deal with a phone call and DriverSpeak at the same time?

I believe echoing is from the volume being too loud. Driverspeak is a great thing to check. The mic may be too sensitive.

Personally, I find talking on the phone in the 2016 a bit of challenge as the signal seems to rarely be strong. Don't know if it's the super quality of the build causing this, however it may be time to invest in a good wilsonamp signal booster.

Being a software guy... the echoing shouldn't be happening period on a standard call... it's digital noise cancellation 101. I can only guess that it has to be one of a couple of things.

1. BT is connecting audio output and not audio input, hence the mic the phone is what's actually being used, not the one in the car.
- this wouldn't surprise me since I haven't seen an update since the iPhone 7 was released (and that's the phone with the issue).
2. There is some kind of echo actually happening - like driverspeak which delays speech for the rear passengers.
- this seems like it would be odd; as I would think driverspeak would be disabled while in a phone call - but I've seen crazier bugs.
3. Is it caused by both parties being on speaker phone and the natural delay of cellular. I'm actually surprised at the amount of delay.

As far as signal - do you have an aftermarket window film installed? Metallic films (as opposed to dyed or ceramic) will hamper all radio signals. Additionally if you're keeping your phone in your pocket - the signal will also be lessened. Otherwise - I've not experienced issues with signal strength - if anything it seems actually better than other cars I've been in.

nether of us on speaker, no tint.

Has anyone found a solution to this problem? Ever since wife switched from her iPhone 5 to 7 we've had this same problem with her 2015 Highlander Limited. Hands free is totally unusable in her car. Vary frustrating.

We've never had Driver Speak enabled. As far as I can tell we have the latest firmware.

Thanks

I would ask your wife to turn down the volume on her end.
I'd ask my wife to not call me unless she was in an ambulance, was getting shaken down by the political police, or Ed McMahon was at the door with a large check to present me. Seriously, I need my man time and whatever it is can wait until I get home. If she's out of milk, she can walk to the store and get it herself.

My wife would reply "Oh, you think I'm too loud!?" Then she might start screaming. haha.

In all seriousness though, here are a couple things to consider with any phone:

1.) Reset network settings. I know the OP mentioned something about this only happens with the iPhone 7 but this is always a good indicator if the problem is happening repeatedly while calling from a specific area. An area is defined by 25-30 mile radius.

2.) Restore the phone and set it up as a brand new phone. In the case of iPhones, do a DFU restore:
http://help.ifixit.com/article/108-dfu-restore

3.) Compare with other phones. Again the OP said it never happened on the previous phone. Let's see what happens when paired with other phones. Different makes and models.

4.) Ask the dealer to either reset and/or upgrade firmware in the stereo unit.

Hopefully the issue has already been resolved but just tossing this out there as general rule for troubleshooting.

I suggested asking his wife to turn down the volume her end because a feedback loop is the quickest, simplest step in troubleshooting. Kind of like for computer repair services that ask people who say their computers are dead if they can check that it's plugged in properly, and more times than not that simplest of issues is the actual problem. It often pays to address the simplest issues first, IMO.

BTW, AYOT4R never updated us to relate if turning down the volume on his end rectified the issue. Updates are nice. :)

It's not caused by her having the volume up too load. If she turns it down any more, she wont be able to hear the caller.

Thanks

Historically speaking, some cars have not been properly magnetically shielded but I don't think it has anything to do with that. You could always have her move the phone to other parts of the car if its not already in the backseat in a purse/bag or anything like that. Other than doing due diligence with the dealer, your next step would be to scheduling a Genius Bar appointment at the Apple Store and possibly getting the phone swapped. If the Genius/Family Room Specialist will not budge, you can request that they come out to your car with you to test it out.

Given that I'm not the only one who's experienced this problem, I'm still hoping someone on this list has already found a solution and will provide an update to this thread.

I've found a few mentions of this problem on the internet but no solutions mentioned, although all the comments I've seen are over a year old. Several have had Toyota look into it without solving the problem. So unless there has been a recent firmware update from Toyota that solves the problem, I suspect there is no fix yet. And if its a problem on Apple's side, they don't have a fix either since we have the latest SW on our phones.

There is an adjustment in the diagnostic mode of the stereo unit for hands free voice quality if you'd like to try it.

1. Enter diagnostic mode - ignition on, screen and audio off - press seek up button 5 times, seek down button 5 times within 15 seconds.

2. Select "function check/setting" from the service menu.

3. Select "HF voice quality setting" from "function check/setting I"

4. Enter "0100" for weak echos heard, "0200" for strong echos heard, then "set"

Note: this comes at the expense of sound quality of the other party.

Setting options:
*Only change the first two digits, the last two should always be 0.
*Numeric values 0 to 2, min to max.
*First digit = Noise (background) level compensation
*Second digit = Echo compensation

Anyone had luck with this issue yet?

I've also got a 2015 Highlander and this echo issue on the receiver's end did not start until I upgraded to an iPhone 7. I've called our local Toyota dealership and talked to a kid who thinks he knows how to fix it. He said there is an echo setting that can be adjusted. (Wondering if it is like the example provided above.) Planning to take my car in and have him try it. So frustrated that this issue has rendered the hands-free phone feature useless.

After further experimentation I believe the problem is on the iPhone side. If my wife puts her iPhone 7 inside the center console the echo nearly disappears. So it seems the microphone on the phone is still active while connected hands-free via bluetooth. Unfortunately I've not been able to find a way to disable the microphone on the iPhone while connected to the car.

Definitely not the first time an Apple product has not 'played nice' with something that was not Apple.
