I have the same car and want to do this, but not for the reasons the author noted but because the GPS unit in the car is broken when paired with Carplay and has the wrong compass heading causing navigation to be completely useless.

I have reported this to Toyota multiple times with videos detailing the problem and they have denied the problem and ultimately when faced with the evidence simply refused to fix it.

I've been a big fan of Toyota's Production System and their management culture, but this experience has really diminished the brand for me. I realize these problems exist with all cars today. The pattern seems to be to foist low-quality hardware and software on their customers and take no responsibility for the results. Software bugs aren't what they consider a "typical car problem" so they simply don't fix them.

I have exactly the same problem in my (latest-model) Honda Civic / Android Auto! I thought I was going crazy, I'm glad to hear someone else has the same problem.

The only fix I've found is to disconnect the phone and use its map standalone, just sending audio over Bluetooth. Maybe it's possible to get Android Auto or Carplay to reject GPS data from the car? I don't know...

I don't work for Toyota, but I do wonder, who exactly within Toyota have you contacted? Maybe you're reaching people who have no idea how to reach out to a real engineer within Toyota?

Stop "reporting this to them multiple times" and sue them.

This is exactly why the civil legal system exists.

I promise you a consumer rights attorney will be interested in going after Toyota if you have clear evidence of it.

Or you could take it to an independent mechanic. It's likely just a bad connection to the "sharkfin".

Nah. It really doesn't, not to the same degree. Consumer Reports has demonstrated this handily for many, many years.

I don't know about internet, but it actually works the other way for GPS; Carplay/Android Auto relay the car's GPS data to your phone, because that is usually more accurate and it means your phone doesn't have to burn battery constantly polling its own GPS.

Some brands take software very seriously. This isn't an "entire industry" problem.

My experience is pretty small; I've owned the same Tesla Model 3 LR for the last 6.5 years, and the software has been pretty much solid the entire time. There was briefly a problem with echos when I called land lines using the bluetooth and my iPhone, but that problem eventually went away - not clear if it was because the iPhone changed, the software was updated, or perhaps the particular landline I was calling got an upgraded CO, but for a car that's a pretty good track record. There were some sensor glitches but they got fixed.

I've test driven other cars. Lucid Air - tons of weird glitches. Rivian - almost as good as the Tesla, but laggy UI on a brand new car. My Tesla is almost seven years old and still smooth as the day it was new! How do they do it?

Compass heading specifically does seem to be unusually challenging. Does anyone else recall the bizarre "Google Maps on iPhone is 90 deg off" problem? Totally strange.
