Introduction

Raspberry Pi can be widely used for Car computer with many features, such as plays DVDs, GPS, displays TV, Bluetooth (phone calls + music), MP3/MPEG4 player, CD/radio, car camera, reversing camera (comes on automatically when I put the car in reverse gear), etc. This week, I test raspberry pi to connect to android phone’s wireless hotpot, and setup camera and display feature as below. It is interesting.
