I have a Volvo C30 with an old 30-pin iPod input. If I plug my old iPod there, I can listen to all the music inside, select it from the car stereo controls, jump tracks from the steering wheel controls and see those track names on the stereo screen.
I want to connect my iPhone to the car via AirPlay or Bluetooth and keep those functions: track name on the screen and controls from the steering wheel.
My first attempt was to jailbreak the iPod and install some packages from Cydia. I didn’t find any way to configure the iPod as a Bluetooth sink, so AiPlay is still the only way and, as I wasn’t either able to create a WiFi hotspot from the iPod, I have to take it out of the glovebox and manually connect it to the iPhone’s just manually enabled hotspot each time I go into the car. A real pain in the neck.
I want to try it now with a Raspberry Pi to iPod HiFi 30-pin-dock Adapter for Airplay Audio Streaming (How to Turn your Raspberry Pi Zero W into an Airplay Streaming Adapter – Poolside Factory) united with a Raspberry Pi Zero W which even takes power from the car’s iPod interface through it.
Now, the point is… if I use Balena and Bluetooth, will it pass the songs metadata through the 30-pin iPod connector? will it respond to steering wheel’s commands and pass them through Bluetooth?
What do you think?
