How bad is Android Auto for privacy on a stock Pixel phone. What can the car and car vendor get access to.

Android Auto is just a projection of the information on your phone so, as far as I know, it's as private as your phone is.

Of course there's always the possibility that the vehicle itself is doing a screen capture and processing the information on the display to send back to their servers but...seems unlikely on account of the processing power required for that.

I was recently very interested to learn that, if I run a VPN on my phone, Auto immediately calls out the VPN as a problem and refuses to connect to my car until it's disconnected.

I'm guessing Android Auto wireless. And if so it makes perfect sense. You can't route everything through a VPN when your connecting to a device with a local network.

[–] [email protected] 14 points 3 days ago (1 children)

I think this has something to do with how networking works.

When connected wireless to my car with a VPN active on my phone, my phone won't connect to my cars WiFi network to initiate the android auto connection.

When connected by USB with VPN active on my phone it's not issue, android auto connects and my VPN is active.

I remember seeing someone smarter explain this a lot better online somewhere then I can at the moment. But simply trying to connect wireless with a VPN active will not work.

This. Some convenience features simply don't play well with non-standard setups and that's fine IMHO. Of course wireless android auto cannot work if you manually overruled how your phone should connect to networks

[–] [email protected] 8 points 3 days ago (2 children)

Is that android auto or wireless android auto?

[–] [email protected] 8 points 3 days ago (2 children)

For me, wireless. Wired still worked through VPN.

[–] [email protected] 6 points 3 days ago

Yeah same experience for me. I assumed it was an issue with the routing table, but manually updating it didn't seem to help. I assumed I was just not good enough at networking on android. I'd believe google would try to crap on that too though.

Wireless android auto hasn't worked with VPN's for years. It's because the service is now baked into the OS, preventing it from split tunneling.

Switch to wired and it'll work

[–] [email protected] 4 points 3 days ago (1 children)

I can get it to work if I whitelist the android auto app from my VPN.

[–] [email protected] 2 points 3 days ago (1 children)

Which means it isn't using the VPN.

[–] [email protected] 2 points 3 days ago

I'm saying split tunnel is very similar to a whitelist and is available to some VPN's. A split tunnel would also bypass the VPN.

Also, while Android auto is a system app now, it is also identifiable by my VPN software and able to be whitelisted.

[–] [email protected] 3 points 3 days ago

Wireless for me also. Actually pretty sure I've never used wired.

I've found that if my VPN is disconnected when I first connect to Android Auto, connecting it after the fact won't cause it to freak out.

My VPN automatically turns on when I'm connected to anything but my home network, so if I start my car at home, when I lose wifi and connect to the cell network I don't have issues.

[–] [email protected] 4 points 3 days ago

That's even more concerning!

[–] [email protected] 6 points 3 days ago (2 children)

I just ran into this too. Had to whitelist the app. Felt dirty and probably is...

[–] [email protected] 3 points 3 days ago

Yeah, agreed.

[–] [email protected] 1 points 3 days ago (1 children)

You guys have no idea what a VPN does or how wireless Android Auto works.

Maybe we're just using VPN's differently than you'd expect. For example, I use Blokada, a local VPN for reducing ad/tracking services embedded in apps. I don't actually send my traffic to a remote server.

[–] [email protected] 12 points 3 days ago (1 children)

Android auto provides notification content to the car. Also of course a virtual screen.

So, there is not much that may be an issue. And you don't habe to share your contact data with your car if you want to do hands free calls. That's a plus

[–] [email protected] 1 points 3 days ago (1 children)

I'd like to hear more about this. When I went to setup Auto on my vehicle, it demanded that I copy all contact information to the head unit, or it would not proceed with pairing and setup. That's when I just shrugged and disconnected my phone. Bluetooth works just fine for me

[–] [email protected] 2 points 3 days ago* (last edited 3 days ago) (1 children)

That may be ab implementation detail of android auto for your car manufacturer. I never needed to sync the contacts in BMW and VW.

I had some troubles with Ford, but there It worked via USB instead of Bluetooth pairing without forced sync.

Edit: I am in Germany, so data protection laws may also be a reason why it works for me

[–] [email protected] 1 points 2 days ago

That makes sense. Mine is a Kenwood aftermarket unit so maybe its a Kenwood thing

[–] [email protected] 3 points 3 days ago (1 children)

I'm guessing Google sell your driving data to insurers?

[–] [email protected] 11 points 3 days ago (1 children)

Per Mozilla, they're already getting that from the car manufacturers.

[–] [email protected] 3 points 3 days ago (1 children)

Except my car is old, and doesn't share it. So this would enable sharing for older vehicles.

[–] [email protected] 3 points 3 days ago (1 children)

I mean, if your car is that old I'm guessing it probably doesn't have Android Auto anyways. There's probably a pretty small overlap between those that have it and those that don't sell data.

[–] [email protected] 4 points 3 days ago (2 children)

People install aftermarket stereos in their cars. Mostly in older vehicles, because trying to replace it in the new vehicles tends to be a disaster.

[–] [email protected] 3 points 2 days ago

Didn't know those supported Android Auto

[–] [email protected] 1 points 3 days ago

Installed a sony screen. I'm tempted, but don't want to share the data.

[–] [email protected] 3 points 3 days ago (2 children)

It requires a Google account so pretty bad.

[–] [email protected] 5 points 3 days ago (2 children)

You can enable it on GrapheneOS AFAIK.

[–] [email protected] 1 points 1 day ago

If this is the case that's awesome and I had no idea.

[–] [email protected] 2 points 3 days ago* (last edited 3 days ago)

Works just fine on grapheneOS

[–] [email protected] 3 points 3 days ago

Well, it doesn't
