Apple CarPlay GPS wrong location issue

I've had no experience of your exact problem myself, but again it would be a problem with the car GPS position being relayed to CarPlay. So it would still likely be fixable by a vehicle software update.

I got a temporary hack, the CarPlay on Suzuki grand Vitara will pick phone gps when connected wireless, removed the lightening cable and voila problem solved.

will be shaking some heads in Suzuki too, maps feedback and apple team

why we get dragged in apple and google fight

Update Kenwood media player in VW T6 

- Apple CarPlay GPS wrong location issue 

Kenwood instructed me to re locate Kenwood GPS antenna on top of the dashboard near windscreen on passenger side. (Current location was on top of unit, under the dashboard)

This has worked and my CarPlay navigation is now working correctly. 

It seems the issue was the GPS antenna was losing accuracy due to poor signal. Kenwood also believe it was made worse by T6 heated windscreen. 

Hope this is helpful 

I’m having the same issue. When having the issue, I have noticed that my compass shows my altitude higher by exactly 10x. I live a 1250 feet elevation. When in CarPlay mode and the navigation isn’t working, my compass would say 12500. I believe that this is why the navigation appears to be intermittent. Pending on where the satellite is, me at 12,000 ft, and if it lines up with the street that I’m actually on.

My car (VW Atlas CrossSport) requires WiFi to be on for CarPlay.

I uninstalled Yandex.Nav, Yandex Map and Google Map.

Now i only have Apple Map on my device and for 2 days my nav works well with CarPlay on 2023 Focus…

I deleted my off-line maps, and that seem to work for now

Same:

1. Fire up Apple Maps, shows EXACTLY where I am.
2. Fire up GAIA GPS and it shows my accuracy as +/- 15 feet
3. Turn on Car Play with my Denon, as soon as it shows up, I move 300 feet NE
4. GAIA GPS shows my accuracy as still +/- 15 feet (WRONG)
5. Disconnect from my Denon, I am back to where I should be
6. Cable to my Honda, and it’s stays accurate.

Dead reconning is the feature where a car will use it’s other sensors to ‘kinda’ keep you in the right spot with a loss of signal but still show you where you are at. This is broken/messed up. For me I felt like this started happening with a firmware upgrade to my Denon.

Yes, GPS loss on busy roads is a bad situation to be in. But it's the car's job to give CarPlay the GPS data. A dealer running diagnostics isn't going to find issues in their own software. And yeah, of course they are going to say it's an Apple problem. Did they update your car system & mapping software to the latest versions?

Do your phone maps show the correct position when not connected via CarPlay? If so, you need a car software update. Just remember that after your dealer has updated system & maps software, it might still show the wrong position. You will need to drive your car for a couple of miles for it to pick up the satellites again, after which the position should fix itself.

I took my VW Atlas 2021 to the dealership and this is what they told me.

There is no repairs at this time. It is on the apple communication side with VW. VW is aware of the concern and it occurred with Apple's latest update. They have no ETA at this moment when the update will be available but it will come over the air, so you we get an alert for the update through the infotainment screen.

When I connect my iPhone to my car and I notice that my gps is off, I check my Compass app. Every time my iPhone Compass app show me about 10 times higher. I live at about 1200 ft of elevation and the compass shows me at 12,000 ft of elevation. As soon as I disconnect my phone from my car, the compass elevation goes back to normal. My theory is that an incorrect altitude could give the illusion that it works sometime and not others.

I’m curious if your compass elevation is changing too.

After months of frustration and considering the various causes and fixes, I think the poor quality GPS signal to the vehicle's GPS device is the primary cause. (See post from June 30, 2023 by dangerman)

Unfortunately, it does not appear that the vehicle makers or Apple care to fix the problem. One fix is to allow the phone to ignore the vehicle's GPS source and choose to use the phone's own location. CrisPistol proposed forcing this manually by disabling the vehicle's GPS source.

9to5Mac has an article about the issue.

Will the problem still exists if you remove the phone and reconnect it *without* enabling wireless CarPlay?

My Issue seems to involve the speed sensor giving data to the radio and the radio is acting like it’s offline and using that data from the 3D Calibration status screen which is causing maps to glitch. Going to disconnect the speed sensor wire next week. This issue does not happen with an android.
