HUD is an abbreviation for heads up display and it is mostly used in aircrafts. and I recently saw an article about an HUD system for GPS navigation in cars. i read the article and i was pretty impressed by how useful it might be. i mean i don't have to get 5 close car crashes while holding my phone. back to the article at the very end in the last paragraph i read something like " this HUD can be bought for 350$". then i was like screw this no HUD for me too much money.

now i thought about it and the concept behind it. and found out i can make my own HUD and the only con is that i have to be familiar with backward reading because the image is flipped so i have to read from right to left not the normal left to right way.

(this is best for GPS navigation and i don't encourage any individual to use it for other things because that might cause a fatal car accident.)

please vote for my instructable in the glovebox gadgets contest and also favorite this instructable cause i wanna get featured so badly after i failed 7 times.
