Due to a growing list of mechanical problems, it was time for my beloved Aurora to be recycled. To replace it I bought a 2000 Nissan Altima, and with a new car comes a new stereo installation. And a new installation means improvements, fixes and of course problems.
This time I added additional circuitry for input switching of four audio inputs, a universal volume control on the output, a usb port, bluetooth, and an auxiliary input. The new circuitry is based around an arduino leonardo and stuffed inside the same project box from the first build, which was a tight fit. Next time I’ll definitely use a bigger box.
