Caller echo with iPhone 12 and Carplay

Just installed Kenwood Stereo for my 2010 Jeep Wrangler Sport with bluetooth and Carplay and I'm having the same echoeing problem. I have an iphone 11pro and who ever calls in has extreme echoeing on their end....I've reached out to apple...jeep dealership and Verizon in trying to figure out the problem before heading back to Banghart's. After trouble shooting with different phones, different USB cables, updating software , lowering volume and moving microphone location, Verizon informed me that the problem is either the wiring used in the install is not compatible or problem with the installation it self or the microphone installed does not have a noise canceling feature....again, the problem is only with the USB not when using bluetooth.

Additionally, a temporary fix if your carrier is Verizon is going to settings....cellular.....cellular data options....voice and data and shutting of "VoLTE" ( a verizon feature) this stops the echoing but you lose access to data during call...which is extremely inconvenient as when you get out of the car ..you have to turn it back on again...on off ..on off ...ridiculous.

There has to be a permanent fix...

Heading back to Banghart's to see what needs to be done..

I have the same issue, but it persisted from my iPhone X to my iPhone 12. I have a 2018 Hyundai Santa Fe Sport, and people keep telling me they hear a strong echo in the background of themselves (probably the car speakers). I just called my wife today while she was in the car (she has an iPhone Xs Max), and I could hear myself echo-ing really bad.

Hello Colinleopower,

Thank you for reaching out in Apple Support Communities. We understand callers are hearing an echo during a phone call with the use of CarPlay in your vehicle. We'll be happy to help.

Excellent job by isolating this behavior with the USB cable. If you haven't tried yet, we suggest to use another USB cable that's connected from your iPhone to the vehicle. Then, test and see if callers continue to hear an echo.

In addition, let's follow the recommended steps outlined here: If you need help with CarPlay

Kind regards.

Colinleopower,

Thanks for getting back to us and for verifying that information. Were you able to follow the article that was previously advised? If not, let's follow each of the steps that's outlined within the article to help troubleshoot CarPlay: If you need help with CarPlay

In addition, you'll want to see if a carrier settings update is available. Here's how: Update your carrier settings on your iPhone or iPad

Cheers.

After much frustration and excessive trouble shooting, we ended up upgrading to an entirely wireless Carplay system...and the echo problem went away 100%....paid a little more but was worth it.
