Hi,

Can anyone confirm if the e-tron has wireless Android Auto? I'm used to using it on USB in another car and an going that when my e-tron arrives it'll work without USB.

Thanks.

The 2019 e-tron has wireless Apple Carplay, but not wireless Android Auto.
Short answer is that Android Auto Wireless uses more bandwidth than can be transmitted over bluetooth. The vehicle's WiFi connection is the way Android Auto Wireless connects, and at this time the e-tron head unit is not certified to be used this way. I could see this being a SW Update.

Thanks Joe. It's a shame that a car that's only just become available doesn't have a head unit that supports Android Auto Wireless, but I'm quite happy to carry on with USB for now. I'd imagine that over the next couple of years, all head units will start to support it.

Any update on this? I find it very annoying, having a super car, etron 55 2020, with a manual usb connection... Installed a wifi card into it for the hotspot, but indeed Android Auto still not wireless. Is there a place at Audi to "Complain"/ "Feedback" these experiences.

 

[tonybkent]

Nothing that I've heard. My e-tron arrives in 2-3 weeks so I'll report back what I find. I'd imagine that that it's coming with the next model year, not mine.

So plugging an Android phone directly via USB still would not activate Android Auto? I took a test drive the other day and the salesperson told me it had both Apple and Android.

Yep, that is correct. They have both Android Auto and Apple Carplay, but it may have been disabled by a previous driver.

SETTINGS -> Connected devices -> Audi smartphone interface -> a smartphone.

Also, a few other common reasons why there are issues:

1. Use the USB ports located in the storage compartment under the front center armrest.
2. Use a better quality USB cable, such as the one your phone shipped with
3. Make sure Android Auto is installed; if so, try to clear it's data/cache, or remove/reinstall.
4. Turn the phone off and back on again.

Page 220 and 229 in the Owner's Manual has more useful information on Media playback, Android Auto, and Apple Carplay.

@fojaker - as far as I know (still a week or two from delivery) it will work over a USB cable. My question was specifically about the wireless version of Android Auto - something that not many manufacturers are supporting yet.

Also, the E-Tron has a pretty darn good stereo system. If you are into high-quality music, you'll always want to plug-in directly. Wireless just doesn't have enough bandwidth to do it justice. All of that compression kills it.

And if you aren't into high-quality music, get a trial of Tidal or Deezer, download some Hi-Fi or Lossless tracks, plug into your car, crank the volume, and enjoy. You won't even care about the cable anymore.

I think you're misunderstanding what WiFi does (Android Auto Wireless uses WiFi). It's just the physical/data link layer that gets your data from one place to another, and while it uses compression, when the data being sent from your phone makes it to the car or any other destination, there's nothing different about it than had you used USB to send it. Think of the compression that WiFi uses as something like a zip file - you know it's compressing the data but once it's uncompressed on the other end, it's indistinguishable from had you not compressed it at all.

Compression of the audio file/content itself is a completely different thing. That's where the codecs come into play, and some do indeed result in loss of data. Bluetooth audio is generally streamed using SBC or AAC codes, both of which introduce some loss, with AAC being better than SBC but not lossless. There are a few others now too but for the point of this post, I'll concede that none of the Bluetooth codecs right now are lossless to my knowledge. While that doesn't mean most people would hear the difference, there could be differences at least from a technical perspective from plugging in via USB.

So using WiFi and specifically Android Auto Wireless routing its data over WiFi should result in the best quality, the same as USB. The benefit to the user is not having to worry about plugging in that cable or having your phone think you want to use Android Auto just because you want to plug your phone in to charge.

Well, you're not wrong. Although if I was expecting a technical discussion, I too would have started with a much longer post to further elaborate.

Without proper context, the word "compression" can mean a lot of things. The point is that in the real world, sending the audio signal over wireless does indeed result in loss of audio quality. There are many factors involved in this beyond simply being wireless, such as the codec, DAC, file type, conversion, etc. Even with wi-fi, you don't exactly have unlimited bandwidth, which is already being shared with other data functions. And then you still need to factor in how the phone and the vehicle will handle and process the signal. Not all are created equal. A USB-C connection isn't except from these factors either. But my guess is that the Wi-Fi standard, that at least CarPlay is using (and maybe Audi), is a bit more loose than with hardwired.

While I've yet to read any whitepapers on the exact specifications or requirements for WiFi-based Android/Apple, I did try it myself. And I wasn't surprised when my iPhone 8 playing Tidal via wireless CarPlay was noticeably less crisp and clear versus hard-wired connection. Will most people notice? If they're already happy with FM/SiriusXM/Bluetooth, perhaps not.

The point was for folks to try lossless music, hardwired, on a stereo that can actually benefit from it, as is the case for the Audi. Then if they do notice the difference, it may not be so easy to go back. And the "hassle" of plugging in your phone may be a non-issue, as it is for me.

Both BMW and Honda is offering wireless android auto..

 

[tonybkent]

My phone now tells me, when connected using Bluetooth, that it knows it's connected to a car that has Android Auto available and to use it I should plug it into the USB cable. Frustrating that it knows, but can't use it!

Still, I'm not that worried as the USB charges the phone too obviously. I didn't spec the wireless charging due to the size and location of the pad meaning I'd have to remove the phone from it's case each time.

AAWireless is a pretty good, cheap and elegant solution to add wireless Android Auto to your car: AAWireless

The 2021 e-trons with MIB3 could technically support wireless Android Auto, VW cars on the same infotainment system support it, but the Audi software doesn't seem ready yet.

 

[maxzuc]

No puedo hacer que Android Auto Wireless funcione. Si puedo hacerlo con USB conectado. Pero cuando intenta usarlo de forma inalámbrica, solo están disponibles las funciones básicas de llamada y reproductor de audio. No hay mapas de Google, etc. I have a Etron SLINE 2022 sportback.

Los e-trons 2021 con MIB3 técnicamente podrían admitir Android Auto inalámbrico, los autos VW en el mismo sistema de información y entretenimiento lo admiten, pero el software Audi aún no parece estar listo.

¿Cómo veo si mi etron tiene MIB3?

Android auto, or Carplay only work if the vehicle has the software enabled (it must have wifi5G to connect to the cell phone in mmi transmission mode). So, I already tried everything, there is no way to do it from behind. The only thing left is that we use usb C cables. I found a way to do it more practical and that does not damage usb connections. I'll give you the link on Amazon, it's a magnetic USB C connector. That means you always only have the short cable in the car, and when you get in the car you connect to the cell phone magnetically.
You can buy the shorter cable, and the magnetic connector.

and this conector https://www.amazon.com/gp/product/B08XX3PQWF/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&th=1

It is what I can do until the manufacturer releases an update with AA without cables.
