Tools for Drivers
20 toolsEverything around the car rather than inside it: build a USB stick the head unit reads in the right order with readable titles, convert video for a headrest screen, look up an OBD-II code before booking a garage, verify a VIN including its check digit, fit wallpaper to the dash screen, set up the speakers and rescue a dashcam clip the recorder never closed.
USB music for a car stereo
Lay the tracks out so the head unit reads every one of them, shows the titles in readable form and plays them in the order you meant.
Video for a car head unit
Bring a clip down to what the screen in the car actually opens: H.264 profile, resolution, audio track and file size.
