Ben, I would love to see your take on a Raspberry Pi Carputer that completely replaces the car stereo. What do you think? Would be a great episode!

hi. i'm building a pi 3 system to put into my car. i've taken the internals from the dvd player out of the after market head unit and i have replaced them with a pi 3, a 120gb ssd, a 3800ah rechargable battery pack, and a pifi dac+ v2.0,
the pi boots directly from the ssd already so no sd card in the sd card slot. i'm going to solder all connections inside the dvd chassis to save room but that's where i come to my limitations. powering the unit is no problem. i have 12v to 5v 3a power supply which will be ignition fed when the ignition key is turned but i need to find a way to shut the pi down correctly, i don't just want to cut the power when the key is turned off. i read your article on fitting a simple on off switch to a pi but again that doesn't allow for a soft power down.
any help you can give would be great
Perhaps take a look at the geocache episode of the Ben Heck Show. If I recall correctly, Ben uses a low power ATtiny45 microcontroller to control the power to a BeagleBone Black in order to power it up and shut it down in a controlled manner.
Another similar approach using an ATtiny44
