He's not a Dr.Any news on this and whether I could purchase it as a kit - or you could install in Cape Town Just don’t take the wrong turn

Bloody awful that, CT not good at the minute. Blooming nutcase Malema et al.Any news on this and whether I could purchase it as a kit - or you could install in Cape Town Just don’t take the wrong turn
Can't see how GPS running on your phone can use anything but the phones own GPS antenna. Not heard of any phone that will take a GPS antenna input somehow!
Unless there is some API where Car play has it's own GPS unit and it somehow sends the location data to the phone, overriding the phones own GPS?

The way CarPlay works in the Aston installation is that it uses the car's own GPS antenna. If that goes screwy, then whatever app you're using doesn't have the first clue where you are. In my case, it wasn't the aerial that was duff but the infotainment module, which went from seeing 12-0-12-0-12-0 etc satellites. Hence it was mostly confused. It then used the phone's own GPS antennae until the phone also lost connectivity and then tried unsuccessfully to rely on the car to tell it where it was.My thoughts exactly. Which while not impossible seems both unlikely and un-necessarily complex for basically zero gain.

Well this piqued my interest, and the view on the tubes was mixed. So I just went down a rabbit hole of Apple developer documentation for Carplay and (while I am not a proper developer, or electrician) I can find absolutely zero mention of GPS data being passed from car to phone (or indeed, vice versa). It may be that I missed it, it may be it's not part of Carplay, it may be different in Android but that's what I foundThe way CarPlay works in the Aston installation is that it uses the car's own GPS antenna.

Not its own antennae, it uses the car's one that serves the OEM satnav.Car play must have it's own GPS gubbins if it's using it's own antenna.

I don't think the data goes from car to phone. CarPlay's just a mirror of the phone screen (pretty much). But the exact location is determined by the car's own GPS aerial rather than just the phone's GPS antenna. Which makes sense, because the phone's likely chucked in a glove box and would have pretty dodgy GPS signal compared to a properly located aerial. As the infotainment module (which does the CarPlay blahblah as well as the native GPS, music etc etc) on mine had gone a bit screwy, the mirrored screen had no real idea where it was, and invariably guessed a few hundred yards away from reality, in a field or a quiet cul-de-sac.Well this piqued my interest, and the view on the tubes was mixed.

So how does the phone use the car's GPS antenna if it is just chucked in the cravat box?I don't think the data goes from car to phone. CarPlay's just a mirror of the phone screen (pretty much).

But it is the phone's satnav app that is shared through carplay surely. The cars GPS cannot talk to the phone or the app.I don't think the data goes from car to phone.

You'd think that... and logically it would make sense (apart from the car aerial being stronger than the phone GPS engine) but it was the failure of the car's satnav capabilities that buggered up all CarPlay nav apps. When the GPS went screwy, the OEM nav and CarPlay got lost. It all went to crarp.But it is the phone's satnav app that is shared through carplay surely.

My Merc thinks it is in the ocean. When I select nav I just get a blue screen. Not that I use it. Might be time to chop it in and be an excuse to add some AMG letters into ownership.You'd think that... and logically it would make sense (apart from the car aerial being stronger than the phone GPS engine) but it was the failure of the car's satnav capabilities that buggered up all CarPlay nav apps.

tbh, it was a head-scratcher for the tech that unfucked it, but the process of elimination narrowed it down to the infotainment module's failure to know where it was. When it sat there flipping between seeing 12, 0, 12, 0 satellites, it was lost. New module and it could see a solid 12 and all worked fine.
Now you're taking! Your man maths calculator is working well.My Merc thinks it is in the ocean. When I select nav I just get a blue screen. Not that I use it. Might be time to chop it in and be an excuse to add some AMG letters into ownership.

Waze use internal GPS. I have never seen it pick up car GPS, but then it rarely loses signal, although mine is never in a glovebox or armrest. When it loses GPS it loses it.This. I think that's all there is to it. The failure of the car system is a red herring. Happy for someone to logically demonstrate where the error is.
As a geek, I would absolutely say it *has* to. If Waze (for example) is running *on the phone* and it's not using internal GPS then the GPS location data *MUST* come from the car *to the phone*
But as ever...anyone want to out tech me, I'll be happy. My team do it regularly

Sorry, I meant the other way around. As far as I know the phone's ability to know where it is should not be influenced by the car's inability to know where it is. So positioning data from car -> phone seems unlikely and unecessary.As a geek, I would absolutely say it *has* to.

What I do know is that there's a separate GPS antenna and CarPlay uses the info from it.
Whilst we are on CarPlay and signal - what could disrupt the CarPlay (wireless) connection between phone and car? And even disconnect Bluetooth completely?
I’m having that problem on my new Defender at specific places. My BMW is fine at those same places.

It's not purely for CarPlay, but handles all infotainment.
