Examples of the present disclosure relate to a device, method, and system for integrating a projection mode of a user mobile device with a terrestrial tuner. In an example, the system may be a vehicle including a head unit and a vehicle projection stack to operate in the head unit. The system may also include a terrestrial tuner communicatively coupled to the vehicle projection stack to receive a terrestrial signal from a terrestrial source. The system may also include an audio driver to provide an audio signal to a vehicle interior where the audio signal is from at least one of the terrestrial signal and an internet signal received at the vehicle projection stack from a user mobile device located inside the vehicle interior.
