I really enjoyed this article! The way you highlighted the suspense and drama of https://fivenightsatfreddys2.io really made me want to play it right away.

I tried disabling the phone location while using Waze and it followed perfectly the route so I think it used the car's GPS antenna. But, after around 30 minutes the app asked me for GPS permission causing the navigation interruption. So, I think that it can be possible and it's something related to the Android permission handling when some events occur

How do you set up Google maps to use car gps?

I've a kenwood dmx8021 and maps asks me to turn on my phone gps

Any plans to implement this?

Desperately needs it. My car blocks cellphone GPS AND I have no alternatives since security policy prohibit android developper Option Allow Mock. I can't even use an external GPS

Waze to use inCar GPS is a must
It is also not understandable nor unbelievable that Google maps does it while Waze not

Need this! Waze keeps freezing the car movements. But when I flick to Gmaps, its flawless. So 100% something wrong with waze app on Android Auto.

Really needed.

Technically Waze wouldn't be using the vehicle's antenna through Android Auto, but instead location information that can be provided by the vehicle to Waze over the Android Auto connection.

I believe this is already working. It does require compatibility between the app, the device the app is running on and the vehicle.

Not sure why this would be so difficult for Waze to use the car's GPS via Android Auto. If GMaps can do it, why not Waze?

I just changed my car and the new one has an athermic windshield, so the GPS signal is too weak inside the car.
Waze becomes useless because the location is not longer precise enough to keep the car on the road. Maps uses the car GPS device and works fine. BTW, no notifications for radars and dangers.
It will be a killer feature for Android Auto and not very complex to implement, maybe just a tick on the settings page to choose between internal or car GPS when in Android Auto mode. Providers are easy to detect and switch using the Android API ;)
Thanks

As you are working on the Waze beacons for tunnels, this could solve this problem, since most of the telematic units in the cars can track the car's location in tunnels as well...
and in general this would solve many issues... Cars are getting more and more "padded" on the inside and outside. Loosing gps signal during phone call is annoying as well and so on so on... Using the car's location data can hit many birds with one stone.
PLease please get this tou your roadmap.
As a product manager on mobility product I recommned this highly.
Thank you

Android auto + Waze + my car = no smartphone GPS. The car does fully block the GPS signal.
thus leading to not possible to use WAZE with Androit Auto.

Only the InCar GPS works.

When will Waze starts to use the InCar GPS ??????

Yes i cannot use waze in my car becaoe of that.

When I receive a call, my phone turns off the integrated GPS.
If I use a car GPS, I can still follow Waze's navigation.

Please put this on the roadmap!

That's the only thing holding me back from using waze as my default navigation app. My phone is located under the dash and the GPS signal is terrible. Google maps is using my cars GPS antenna which results in an excellent accuracy.

This is highly required as I've noticed the GPS signals not as accurate/responsive as they were in my old car before I started using Android Auto.. My new car has a wireless charging dock for the phone which is essentially under the dash which is making the GPS signal weak... It makes sense to use the cards GSP receiver as it will be a lot more accurate and better positioned...

Also wish to strongly lend my support to this suggestion, though it looks like Waze don't care.

I just learned this and so, switched back to Google Maps with Android Auto. I was wondering why Waze seemed to take a long time acquire initial location and respond to turns not recommended by Waze navigation. Now we know why.

Indeed reception on my Civic '17 while using Waze was poor. The phone was buried under the center console.

How do you know Waze uses the internal GPS antenna ? Please also note, a phone can support many satellite system like GPS, GLONASS, BEIDOU, GALILEO, QZSS (my Huawei Mate 20 do) while the car infortainment system normally only support the 1st one, the current model could support the second one. This could lead to phone can have a better location sensitivity, even it use the its own, internal antenna. The only exception, is the car can offer all five satllite signals to phone, which I think it is quite unlikely right now.
