For those of you who have a rapsberry pi laying around (or need an excuse to buy one), you can set this up yourself.
I’ve installed it on a Raspberry Pi Zero 2 W and it works as expected. Only downside I see is switching between my and my wife’s device (the Motorola device has a physical button for this).
Oh that’s neat! Do you need 2 USB cables connected to the PI, 1 for data connection and 1 for power?
One is enough for my setup. It depends on the car though, the raspberry needs 2 A /10 W. If your car doesn’t provide enough energy, you might need another power source (e.g. a small power supply powered by that cigarette port.)
Ok thanks!
Do the little bluetooth dongle-thingies i’ve seen on AliExpress work?
Yes. Both my brother and father bought the aliexpress dongle because Opel and Ford implementations were shit.
Yeah but they drain your battery because what you see on your car’s display is rendered and streamed by the phone. A cable is much more efficient in terms of power per data sent, plus it provides power back to the phone.
