OTA Updates
OTA Updates (Over-The-Air Updates) is a way of updating software in cars and infotainment systems remotely, similar to how your smartphone gets updates without visiting a store. This technology lets car companies fix problems, add new features, or improve performance by sending updates through the internet directly to vehicles. It's becoming increasingly important in modern vehicles because it saves time and money compared to bringing cars to dealerships for software updates. Think of it like having a mechanic who can fix your car's computer systems from anywhere in the world.
