i/o for this project
Using this reference https://www.raspberrypi.org/documentation/usage/gpio-plus-and-raspi2/README.mdand https://sites.google.com/site/semilleroadt/raspberry-pi-tutorials/gpio
Used a 4 pin floppy disk connector on physical pins 7,9,11,13 which equates to IO4,GND,IO17,IO27.
The connector has fly leads of yellow (io4), black (gnd), black (IO17), red (IO27). The black was useful as a gnd for first testing IO but both black lead was then snipped.
GPIO Port 4 for HOLD (setting as 1 sets GPIO 4 to 3.3v)
sudo su
echo 4 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio4/direction
echo 1 > /sys/class/gpio/gpio4/value
notes, this is obviously volatile... on reboot GPIO4 is high appears high, but is actually floating. It appears to drop low when direction is set to 'out'
GPIO Port 27 for ACC IN (Set as 3.3V when power is plugged in to the ACC+12V)
sudo su
echo 27 > /sys/class/gpio/export
echo in > /sys/class/gpio/gpio27/direction
cat /sys/class/gpio/gpio27/value
Audio Output
HF: Sound output of some sort to a small speaker (I2S?), also 3.5mm audio to car audio input. Hardware switch to turn small speaker off (for music play etc)Ordered one of these... can get cheaper/similar but this should do

Pi Camera Snapshots and Video
Pi Cam getting started https://www.raspberrypi.org/learning/getting-started-with-picamera/Pi Cam basics https://thepihut.com/blogs/raspberry-pi-tutorials/16021420-how-to-install-use-the-raspberry-pi-camera
More Pi Camera & Python info http://www.makeuseof.com/tag/raspberry-pi-camera-module/
Dashcam Video Store
- Connect dashcam via usb to pi, remove files from dashcam when stationary... upload to server when in wifi rangeMusic Server
- MPD server- sync of music when in wifi range
Navigation
Some sort of audio only navigation... i.e. select preset from menu, audio navigation?http://www.gpsdrive.de/features.shtml
