Comment on Part 2 of car Raspberry pi 4 GPS project

For the audio, I’ll first try the obvious and plug the Pi to the USB A of the factory car unit. Maybe it’ll detect it as mass storage media and give it access to the built in audio system. Else, I’ll just use a bluetooth speaker I have at home. I don’t need good audio for “turn left/turn right”, just to hear it.

The whole project is an attempt at getting rid of Android Auto and having my own standalone unit that will free me from unwanted updates both from the OS and the apps. I’ve had Waze become useless three times in the span of two years because they pushed updates that made the app unstable enough to not be reliable.

For the viewing angle, on the car next to the existing head unit screen, there’s a mounting bracket. I’ll use that to mount a 7inch display I got. It’ll sit right above the existing one if that doesn’t obstruct the view too much, else I’ll have to get one of those arms with joints and lower it somewhere not annoying. Image

My bluetooth speaker is the perfect size to sit in the cup holder so if the car audio isn’t possible, then there’s a plan B.

I’ll try the recovery mode for my phone and see if that helps!

It won’t. Both will be acting as host, so thats not going to work out.

What car do you have?

Didn’t you want to use it for your music as well with navidrome?

CoMaps may be up your alley, uses OSM.

Hope that works for you regardless, it was an absolute pain when my wife’s phone update (Samsung) broke android auto and Bluetooth connections. Especially since I just bought the car a few weeks before.

  Thanks for the CoMaps pointer, didn’t know about that / issues with Organic Maps

  Fwiw, pi zeros have USB host & device/gadget modes, but I doubt a zero would have enough power to do what you need

  What car do you have? Dacia Sandero Stepway
  
  Didn’t you want to use it for your music as well with navidrome? Maybe, if the USB port works, then I’ll use Navidrome on it and put the music that way through the car speaker. If they don’t, I can plug my phone to the car speakers and the Pi to bluetooth external speakers. The phone only crashes during satnav. By the way I did a recovery reset, i’ll try a drive today and see how it goes.
  
  CoMaps may be up your alley, uses OSM. Thanks for the name, current app in testing is OsmAnd, as i’ve seen it recommended a lot. If it doesn’t work I’ll try CoMaps.
  
  Especially since I just bought the car a few weeks before. I feel you, this phone was bought specifically for car use. My former one was slow, but I don’t use my phone much so there was no point in upgrading. I got the Oppo A51 back then because it had decent reviews for the price and I had a deal on it. But I think it’s not beefy enough. It thermal throttles very easily, too.
