Checkout http://da2a.com/Visual Information Display.svg it can have 9 -(L3~L10) 20 segment LED displays, bright sun light readable and fits in a 2.25 space. I looked at using 2" to 7" displays but they are hard to read unless you spend big bucks ($180~$500). This works and you can zoom so the display shows 5 degree per led segment, CHT, EGT, Flaps, Trim, oil pressure, oil temperature, turbo pressure, turbo intake temperature, fuel, voltage. This version is runs AirCan, CAN buss software, the next version will have Ethernet, Bluetooth and AirCan. What I wanted was to pair my phone with my plane, listen to my music and if interrupted by the radio squelch the phone while I work the radio and alert me with audio if something goes out of bounds. I looked at the EMS units at Aircraft Spruce, my plane cost less.
