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.
Car tools
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.
OBD-II fault codes
Paste everything the scanner showed. The reading covers each code and, more importantly, what they mean together — that is usually where the real cause is.
VIN decoder
A character-by-character reading of all seventeen: country, manufacturer, model year, and the check digit that catches a re-stamped number.
Head unit wallpaper and boot logo
A startup logo and wallpaper sized to your model’s screen — with an interface mock-up over the frame and a measured icon legibility.
Car Paint Code Lookup
Type a make, the code from the label or a VIN — or take a photo of the label, and the tool finds the paint code on it.
Dash Cam
Turn a phone into a dash cam in the browser: loop recording, crash save by G-sensor, speed and time burned into the video, GPX trip track.
Video
