Is my car compatible with AutoPi?
Is your car newer than 1996 (US) or 2001 (EU)? Then the short answer is YES. This is why:
History behind OBD-II
The AutoPi dongle communicates with your car through the OBD-II port of the car. OBD (On-Board Diagnostics) is a communication standard available in all cars after 1996, where it was made mandatory by law. It became mandatory in the European Union after 2001 for gasoline vehicles and 2004 for diesel vehicles. With the new port, all cars implemented a standard communication bus, which original purpose was the retrieve environmental telemetrics about the vehicle for classification.
Today the OBD port is normally used by a repair technician for debugging purposes, as a part of the OBD standard is providing real-time trouble codes from your car. This is also what some vehicle models will display in the dashboard. But the OBD protocol contains much more information than what you see in the dashboard. This is why it is such an excellent starting point for making your car smarter.
Where is the OBD port located?
The OBD port is normally located under the dashboard of your car. Sometimes directly below the dashboard, sometimes behind a small hatch or near the ashtray. It varies from model and make. You will be looking for a connector similar to this:
This is where the AutoPi is plugged in. If you have trouble locating the OBD port, you may be able to find additional help in the owner’s manual of your car.
Can I be sure my car is compatible?
If you want to be 100% sure your car is compatible with the AutoPi, you can look for a sticker similar to the one shown above (vehicle information sticker). Is normally located below your dashboard, close to the OBD port. Sometimes it’s located under the hood in the engine room, it varies from model.
If your vehicle don’t support the OBD standard, but still has an OBD port you may be able to use a subset of the features in the AutoPi dongle.

Speak to your car with Google Assistant - almost like K.I.T.T. from Knight Rider
Wouldn’t it be cool if you could speak to your car and give it commands? We remember our childhood in the last millennium where Michael Knight (David Hasselhoff) and his intelligent Pontiac Trans Am named K.I.T.T. solved crime together. While we may not be able to have a meaningful conversation with our car just yet, it’s now a possibility to talk to your car and give it commands to execute. We are here giving a short introduction to how this can be accomplished using the AutoPi.io system and Google Assistant.
Build your own Black Ice Detection system for your car using AutoPi
The term “Black ice” refer to a winter phenomenon, where a layer of ice on the road is so thin it becomes transparent and thus appears “black” from the road below. This is a very common situation during winter times and can create hazardous situations for vehicles and pedestrians. The phenomenon often occurs when the temperature is right around freezing point and when a light rain hits a road surface which is below freezing point.
Saving your car interior on a hot day - Making a cabin overheating protection system using AutoPi
Studies show that on a hot summer day the temperature inside your vehicle will rise dramatically within just 10 minutes after you parked. HeatKill.org reports that with an outside temperature of 27 C (80 F), the inside temperature could rise to as high as 37 C (99 F) after just 10 minutes. The inside of your car becomes an oven roasting your interior. The sun will permanently damage the color and look of everything it touches, thereby degrading the value of your car.
