Ugh. This was nearly a rant, but I'm asking the hive mind.
TLDR: all the big tech companies have killed all the good ways of using my phone in the car.
The car: 2013 Honda CR-Z EX. Factory head unit. Nice phone holder. Analog aux jack. USB supports iPod and MP3 through a crappy single line display. Bluetooth only for phone calls.
The phone: Samsung Galaxy Xcover Pro. Has headphone jack, usb C. Android 12.
Apps: I have local files, Spotify Premium, YouTube music Premium and a little Bandcamp. Google Maps.
Rant: I don't want a new car, or a new head unit. I don't have protected parking. I don't want more dohickeys than an aux cable and a phone mount. I need an app that keeps the screen on, and gives me touch access through a simplified interface to Spotify Premium or YouTube Music Premium and navigation.
Google used to offer Android Auto on the phone screen. They killed that. They then offered Google Assistant Driving Mode, which looked different, but still offered the key features: big buttons, media controls, navigation, a simplified interface, and keeping the screen unlocked. They apparently killed that last month. My driving mode shortcut doesn't work anymore, and now, asking assistant for driving mode gets a Maps screen that has a larger than standard ui. It'll show media controls, only if you start a song from voice.
Spotify offered a car mode, but they killed it to offer Car Thing hardware, which was a screen that only does Spotify, then they killed that after only a couple of months, and never brought car mode back.
Samsung used to offer a Car Mode app, but that appears to be gone.
What's out there from a reputable source that will keep the screen on, and provide a good interface to navigation and music?
