Daniel Stinebaugh wanted to replace his Chevy’s failing head unit with a Raspberry Pi. So, he ripped the old one out and fitted the Pi and a wireless router in it’s place. The Pi runs Volumio and he’s also using the DAC+ HAT from HiFiBerry to route the signal to an amplifier. Read more about the project here. He’s been left with a system which is, in his opinion, vastly superior to any head unit out there with a lot of flexibility and gorgeous sound.
