Evening all.

I built a Raspberry Pi based Android Auto receiver into my '73 Triumph TR6.



I'm quite enjoying the juxtaposition.

It's got a tiny 400W amp off a nice RCA DAC on the Pi. Then a set of cheek speakers in the tunnel cheeks, a set behind the seats in the corners of the cubby, and a small underseat sub.

Bluetooth and all the trimmings. Delicious.

Looks great! Could you give a few more details around how you set up the Raspberry Pi to run it? Which screen did you use?

Yes indeed!

It's a Raspberry 3B+ with a HiFi Berry Dac+ (RCA out) running Open Auto Pro.

I'm using the Raspberry Pi 7" Touch screen as-is and building a stack off the back of it with the Pi and the DAC. Nicely the posts on the back of the Screen exactly fit through the din slot. Meaning that the mounting was a breeze as everything lined up nicely.

I'm then using a 5A 12-5V converter to run the whole lot.

A 400w Kenwood micro amp handles the RCA and the 4 speakers, with a splitter to the Sub.

You'll also need a USB soundcard (as Open Auto Pro needs a Mic input to work) I used a cheap amazon headphone/mic USB sound card.

After that, there's a little config to get the HifiBerry Dac to be the default out and the rest is pretty much good to go.

I've got the whole lot running via 2 relays, one is the main 12v from the battery, another on the accessory 12v which feeds back into the main relay for the battery 12v.

Meaning the single switch on the left of the second picture powers up both sides of the system, but means I cannot leave it running when I turn off the car and or have it parasitically drain the battery.

The switch is mounted to a 3d printed cradle hanging off the tunnel cheek panel above the speaker, which holds my phone against the tunnel on that side and lets the phone usb port be easily accessible.

Thanks so much for the detailed reply. I've been considering attempting something similar, it's good to see someone's had some success with it!
