Nope. I've been driving the same car for the past two years. And I've had the same phone since last September when it came out. Nothing has changed in the car, other than the navigation system update I installed last week. I wonder if that somehow neutered Apple CarPlay....

I don't think so though, because even if I *don't* plug in my phone, and just open Apple Maps on my phone and stare at it, the same issues persist. It seems to get *slightly* better with each passing day. Maybe by the end of the week it'll be perfect again. Maybe it'll coincide with the Northeast update.

...Or new beta today (assuming public comes out as well).

That will be interesting. I'm fascinated by this change in behavior, even with same phone and same car and not on a beta, so same iOS. I am suspicious of the update to your car nav system, though...

If I can link up with my friend today or tomorrow, I'll plug into his car and see what happens.

I had another thought...the only other new "thing" introduced into my car is my brand new Apple Card in my wallet. What the hell is that thing made of? lol

So I had a weird hiccup today. Left home to head out somewhere, and noticed immediately that Apple Maps was having a temper tantrum. While navigating on Apple CarPlay, all road labels were missing, including the name of the road I was on, which I've never seen missing before. However, my GPS was tracking my movements perfectly.

While at a red light, I decided to cancel my route, and then reload it, to see if switching out of navigation mode and back into it would correct the road labels issue. It didn't. Instead, the map hardly loaded at all. Check out this funk:

After picking up my mother, I rebooted my phone, and reconnected it to CarPlay. Everything was fine after that. (Although I'm usually still an annoying circle when first opening Maps.)

In fact, while I was sitting at the restaurant, I was playing with Maps on my phone, and the buildings looked a bit...better? I dunno, but the map looked really good. Nothing new added, it just looks nice. lol

And yes, it showed me facing the correct direction inside the restaurant.

Checking out AM under PB7 ...
Where before AM would either show one or two routes for Point A to B (was reported), for the same route is only shows one option. Can open and close, kill and relaunch, only get one.

Well, looking at your route, the surrounding roads, and the fact that there's no traffic...how many more routes do you want Apple Maps to show you? It's clearly giving you the best route. Any other route looks like it would add significant travel time, since I'm not seeing any parallel highways.

PB 1-5 it showed 2. Traffic may adjust but almost always had 2 or more.
With PB6 started seeing either 2 or 1. Could run it repeatedly at any time and the 2 or 1 appeared random.
With PB7 down to only 1.

If I run GM on iOS I get 2 or more.
If I run GM on my Android I get 3 or more.

Running it right now, AM gives 1 route, GM gives 2, and GM on Android gives 4.

Been using this as a baseline as my other half drives this daily. I drive it if I drive her in or we go shopping in that location. Great for checking arrival time comparisons.

Well boys...I'm at a loss here.

Nothing was really improved during the early afternoon today. While in my building's garage or in a parking lot, Apple Maps had no idea where I was. Just a vague circle, although the circle was fairly accurately placed. I had to take my mother into Manhattan for a doctor's appointment. Everything was fine while navigating. Until I got into the Queens-Midtown Tunnel, when Apple Maps more or less froze until I came out the other side. Driving around the East Side, Apple Maps was having trouble keeping up. I pulled into a multi-level, above ground parking garage, and Maps lost me completely. I became a circle, and I was floating around all over the map.

But when I went back to my car later and started up Apple Maps, it positioned me correctly, AND had me facing the right way! Not only that, but it tracked me PERFECTLY through that same parking garage! Definitely a major step in the right direction. Maps lost me again driving through the Midtown Tunnel back into Queens, but was fine the rest of the way. It even tracked me through my garage at home.

I went out to visit my friend in the evening, and it worked pretty well, although I was a circle when I first loaded Maps in my garage again. I turned off navigation while looking for parking, and Maps tracked me perfectly.

I decided to test things in my friend's car, so we went out later, and I plugged into his car to use his Apple CarPlay. We drove around his neighborhood without navigating, and everything was perfect. We even turned down tiny private roads, and took bizarre turns, and the CarPlay in his car tracked us without any issues at all. I thought that maybe things were back to normal with my phone.

I was wrong.

We parked, and jumped back into my car. Immediately, Apple Maps had no idea where I was. Even had me facing the wrong way. I made a bunch of turns, and Maps didn't even think I was on a road. It was the worst I've seen it in a week. We pulled over, and plugged in my friend's phone into my car. No improvement. His phone was just as bad. Uh-oh.

We thought maybe it was the USB cable in my car, so we swapped it out for his, but there was no improvement at all. We continued driving, and it was really bad. Even his phone, which he was holding in his hand, was having some trouble tracking us, although it wasn't as bad as my phone, which was plugged in, and secured in its little cubby hole in the center console.

Based on everything that happened today, I don't know what to think. It seems like there's something about being inside my car that's causing our GPS signals to weaken somehow. Yet, things were almost perfect this afternoon. It seemed to be getting better, and the worst of the problems were only intermittent. Guess I'll give it a few more days.

In other news, I saw something interesting on my phone today. When I swiped left on the homescreen to get into the widgets and such, my Maps widget mentioned that my car was parked on the Grand Central Parkway Service Road North. Which it was. That's totally true. But Maps refers to that road as simply "Grand Central Parkway", which is also what the street signs show. It *is* a service road, but I've never seen Maps refer to it as such. When I saw a photo of the new Maps on Reddit, the service road there was shown as "Grand Central Pkwy Frontage Rd". Very interesting. More changing behind the scenes....

I went digging through the Apple Support forums, and found a few topics about this. Most people believe that, when your iPhone is plugged into your car to utilize CarPlay, that CarPlay pulls certain information from your car's GPS or head unit to be more specific regarding your speed and location. That would lead credence to my observation that this nonsense began after updating my car's infotainment system to the latest software.

Although, one person had this to say:


Hi, and thank you both for your replies. However, both I and Apple disagree. Yes, I read the whole thread, so I saw the replies where it was suggested that the car manufacturer is at fault. However, if you read the entire thread, you will see people have this identical issue with Fords, Porches, Subarus, GMCs, and others. If it is an issue with Ford's system, it is apparently an issue with every car maker mentioned in this (and the other, numerous) threads. That alone suggests strongly the problem is Apple's, not the various car makers.


Second, yes, I and most in this thread know that CarPlay derives its GPS from the car when on USB, not the phone. So, it is mysterious that, as I specifically wrote (and have others) the GPS in the vehicle is completely accurate using its own navigation screen. It is only when interfacing with CarPlay that things run amok. This factor alone is not indicative of whose system is at fault in corrupting the transfer of data from the car's GPS to the iPhone, but it shows that CarPlay is the conduit for the fault.


Third, posts in this and the other numerous threads, in this and other forums, suggest the problem is intermittent. Mine is no different. I took three car trips yesterday around my city. I posted after the first. The second trip yielded perfect results on CarPlay--exact/correct locations found on each map app. The third trip had the issue again. My one trip so far this morning had no issue at all.


Finally, and maybe what I should have led with, yesterday evening, I went to the Genius Bar at my Apple Store and asked about the issue. The Apple Store employee stated, unequivocally, that this is a known issue with CarPlay, and is being worked on at Apple.


I probably should have just gone straight to the Apple Store before posting here, but, I'd just done a Google search, and thought I'd add my similar experience. I've owned Apple products for 34 years. I find it frustrating when they don't acknowledge a problem that seems widely reported on Internet forums, but, since the Apple employee last night fully acknowledged that this was an Apple problem, and that they are working on it, that's good enough for me; I wanted to pass that on to others in this thread who have been having this problem crop up. Thanks.

So, I dunno right now. I'm going to look into doing a hard reboot of my car's systems, and see if that helps. It's possible they only go into a "sleep mode" when the car is off.
[doublepost=1566528081][/doublepost]Someone said this, back on April 30:

Contact Ford. The head unit needs to be updated. Changes were applied recently to the Global GPS system to account for drift of the magnetic pole. The nav unit in the car is probably using an old database that does not account for the change. When you plug the phone into the head unit, it gets GPS data from the head unit instead of the phones own built in GPS.

That's interesting. I *did* notice that the compass on my car's rear view mirror seems to be a bit off. Like when I'm heading east, my mirror says I'm going southeast. They rarely match up.

Well, none of this really helps and I'll say that up front, but I did want to chime in with my experience. The GPS in your car absolutely can be used - it's been a core part of CarPlay from the beginning - as long as the car's integration includes it, and it should improve GPS precision greatly. I found the car is around twice as precise as the best the phone can manage using GPS Diagnostic on the phone.

As for the head unit needing updating, I'm a bit unsure about that. My Mustang is just under two years old and I did self-apply Sync 3 v3.0 about (roughly) a year ago but I never had problems with Nav accuracy before or after. With that said, your car's own compass being incorrect does sound like something that might require dealer attention.

I've just sent out two messages to Genesis. One through the MyGenesis owner's site, and one through the Genesis map updates page. I'll let you know if I hear back.

Meantime, I'm going to head out tonight (probably to White Castle), and do some more investigating.

Got the updated maps sometime today in NJ. Just noticed now so haven’t had a chance to test them out yet.

*insert disappointed Ravage and Whiz posts*

On the topic of good news, I fixed my problem. It was my car all along. I did a hard reset of my entire head unit after removing the new SD card for the nav system. After putting it all back together, Apple CarPlay navigation is 100% fixed. Thank goodness.

Also, my rear view mirror compass was programmed for the wrong compass zone. So I corrected that, also. Unsure if that contributed somehow.

As I was reading @G1Ravage ‘s post, I was hoping you would jump in. This really sounds like a car issue, especially since this is happening in 12.4 and it coincided with the head unit upgrade.

I had similar issues with 2 different GMC Yukons but no other vehicles. So it’s either something in the interface or there is something in the vehicle electronics that is interfering.

Edit: just saw the good news from @G1Ravage. I’m going to bet the compass thing was it. The phone probably checks the vehicle compass reading vs its own and that probably always yielded an error.

Here’s the center off my smallish New England town. Way more POIs!

They nailed the sand traps on the local golf course, too!

Look at this detail of NYC! I think the darker shaded buildings (the best known ones) have more detail

Although, here is NYC in “old” Maps from my iPad. Generally the same detail, but the texture seems better on the new but hard to tell for sure. Central Park definitely has more detail though

Well it’s not immune to errors. This building doesn’t exist in real life. It’s right in the middle of the village green (it’s probably misplaced from across the street). Not sure how to report that. There’s no Report a Problem button associated with it.
