Part of what makes ALLDATA Diagnostics such a game-changer is that the VCI (Vehicle Connection Interface) device that attaches to the vehicle’s OBD port is included in the subscription, eliminating hefty up-front costs. And there’s no charge for software/data updates, either. Plus, you can use your own Android, Windows 10, or iOS tablet. Don’t have a tablet? Don’t worry, we’ll put together a custom bundle for you.
