some other ideas for the creative little goblins on this internet forum:

• get a carplay license from apple and develop full carplay support, surely the esp32 can send the display as a video stream over usb and still have headroom to decode audio, it is afterall, very fast, many megahertz in fact
  
• many head units also have a cd changer port which is typically some kind of vendor-specific uart command channel so tangara could emulate a cd changer, if like me your car is from the 90s and your head unit from the 00s
  
• another stupid but awesome idea would be to connect an i2c canbus chip to the faceplate connector and have a dedicated in-car tangara for cars with canbus, this would make your car much more valuable and be a fun project
  
• another thing that works is fumbling awkwardly and dangerously with the tangara unit itself and just hooking up the headphone out to the aux on the car stereo
  
• if your car doesn't have aux you can use one of these
  
• voice control faceplate "TANGARA PLAY THE NEXT SONG"
