Everything works in Apple CarPlay except navigation apps

I recently bought a new car (Mercedes Benz CLA 180) and tried using Apple CarPlay in it. Everything else works except navigation apps. When I use either Google maps or Apple maps, the current location gets constantly switched between the actual current location and somewhere in the middle of the sea near Thailand every now and then. Even apps like Find iPhone also shows the same incorrect location when maps are showing the wrong location. All apps works fine when not using CarPlay.

I tested with two iPhone X devices (mine and my wife's) with iOS 12 and I see the same issue on both.

Tested with an iPhone 6s running iOS 11 and still the GPS issue is there.

Tested with Google Maps on Android Auto on my brothers phone and it works correctly!

Has anyone ever seen anything similar?

I tried with iOS 13 and it seems the issue I have mentioned in the first post is fixed now.

However, GPS coordinates received are still slightly off from my actual location. Some apps like Waze seems to handle these errors but Google Maps sometimes goes haywire and starts rerouting.

I did check the firmware version in my head unit. It is the latest as per Alpine information page.

Good point, it is most likely the phone's GPS, which would make sense. Going to try with 12.1.3 today and will report back.

I called the tech support number here. I called back today to check on the antenna shipment and had no trouble getting through. Hopefully it’ll arrive in the next couple days.

I took my Dodge Challenger to the dealership and they called their support who told them to update the firmware on the stock head unit. It seems to have fixed the problem. It’s worked fine al week.

Honda replaced my entire head unit and that didn’t fix it. But that was last year. It would be interesting to know if there is a firmware update for it.

It’s been a week since the Dodge dealership updated the software on the head unit in the car and I haven’t had any issues since. It’s great.

Hi again

I have tried to upgrade to 12.3 and last here today I upgraded to 12.3.1.

They still give me the same issues.

So no IOS update helps

My issue actually started AFTER I restored my phone - I had another Apple issue so restored my phone - and NOW my navigation apps are messed up when using CarPlay

Mine definitely happens way less than 2 hours into a drive, which is pretty rare for me. I've had it happen 3 minutes into a drive before. Or 10 minutes. Definitely doesn't seem related to time.
