There's more on this link- Now here's something to get excited about!
Makerfire 7-Inch. Raspberry Pi LCD Display Screen TFT Monitor with HDMI VGA Input Driver Board
This thing is only $40!!!
Add in a numeric keypad and you have a basic GPS. But don't forget to get the free Enhanced Garmin 500W GPS Unit (500WX) from Kronzky's Flight Simulator Addons. That FREE GPS software will let you display the entire GPS screen WITHOUT the non-screen parts (no buttons or knobs taking up screen space).
Also, you'll need another free program called HIDMacros to program the keypad, unless you have the paid version of SPAD.neXt.
What you get
BTW -that last picture is from Windows 10, the dispaly will do 1920 X 1080. No problem. That is if you have excellent eyesight.
