The Rise of Over-the-Air (OTA) Updates: What Makes Your Car More Like a Smartphone
Over the past few years, the landscape of the automobile in India has changed, where a smartphone has been forcefully fused into cars with features, that were only seen in smartphones a few years back, have become part of the car equipage. Among the most revolutionary is Over-the-Air (OTA) updates, which allow car makers to remotely update your car’s software without having to visit a service center. OTA updates are increasingly becoming a standard offering in new cars, improving performance, enabling new features, and keeping software secure, all on your terms.
What Are OTA Updates in Cars?
OTA updates refer to Over-the-Air updates, meaning the software or firmware upgrades are transmitted wirelessly to your car, delivered by an internet connection—via Wi-Fi, LTE, or 5G networks. Much like your phone gets system updates over the air, your car can now be downloaded up-to-the-minute upgrades for its infotainment systems, navigation maps, driver assistance features and even engine control software all without stepping foot into a dealership or service center.
Importance of OTA Updates for Indian Customers
The OTA technology brings few practical benefits for Indian drivers as follows:
- Saves you a trip: Download and install updates on your own time, instead of wasting trips to the service center which is time-consuming and costly as well.
- Cost Savings: Skip the expensive software upgrade to get better performance remotely.
- Improved Safety: OTAs allow to quickly fix bugs and update driver assistance systems to keep your car competent for Indian road conditions, which can be both diverse and harsh.
- Add new features and apps over time, and make your car smarter and future-ready content.
- Decreased depreciation of the vehicle: The steady situation of the software can keep your automobile in its best shape and even increase its resale value.
OTA Updates On Popular Indian Cars
OTA technology has been adopted by many Indian and global brands, now providing it in even the most affordable price segments:
- MG Motor India: Aside from the MG Hector, ZS EV, MG Astor and Gloster all feature OTA updates over the air with minimal fuss.
- Over-the-air enabled Tata Motors: Harrier and Safari
- Maruti Suzuki: Vitara Brezza, Baleno, XL6, Ertiga, and Fronx (OTA update support)
- XUV700 comes with OTA updates for both infotainment and safety systems – Mahindra
- Hyundai: All new models, including EVs like the Kona Electric, equipped with OTA-enabled Blue Link tech.
- Kia: Kia Connect for OTA features on Seltos and other models
- Toyota Urban Cruiser Taisor: OTA update capability as well.
Over-The-Air Gadgets and Devices
Most OTA updates are integrated into the vehicle’s onboard system and managed by the manufacturer, but there are also aftermarket solutions that can add some connectivity and convenience for older vehicles:
- Over The Air (OTA) Capable OBD-II Dongles: These plug right into many vehicles OBD-II port and provide remote diagnostics and software to compatible Cars Companies like DigiMotive and GoMechanic sell such dongles, which are typically priced in the range of ₹3,000 to ₹7,000.
- Connected Car Devices: Similar to how Hyundai Blue Link or Tata’s connected car modules work, these connected car devices come pre-installed in new vehicles and provide subscription-based OTA services at a highly competitive price when bundled with infotainment upgrades.
- Phone Apps: Phones are the other obvious partner in OTA-enabled cars, with lots of manufacturers providing smartphone apps that make OTA updates, diagnostics, and remote control of the car feasible.
Cost Efficiency and Quality
The OTA service typically comes as part of the ownership package of OTA-ready vehicles, thereby incurring little, if at all, in incremental costs. For non-native OTA vehicles, low-cost OBD-II devices can be decent value, providing relatively stable connectivity along with the ability to receive over-the-air updates that enhance vehicle health monitoring and provide limited software upgrades.
Frequently Asked Questions(FAQs)
Not all cars in India currently support OTA updates. This feature is primarily available in mid to premium segment cars from brands like MG Motors, Tata Motors, Hyundai, Maruti Suzuki, Mahindra, and Kia. The adoption of OTA is increasing rapidly, and by 2025, more affordable models are also expected to include this convenience. The technology is still emerging, and many entry-level cars may not have OTA capabilities yet, but this trend is expanding with the rise of connected cars in India.
OTA updates depend on stable internet connectivity, typically through 4G LTE or increasingly 5G networks, which are rapidly expanding across India. When your car is connected to a reliable network, usually during idle periods or when parked, the software update is securely downloaded and installed without user intervention. Manufacturers ensure updates occur in low-traffic usage times to avoid inconveniences and interruptions during driving, making the process seamless and user-friendly for Indian road conditions.
Yes, OTA updates use robust encryption and secure authentication protocols to protect the software from unauthorized access or tampering. Automotive companies implement multi-layered security measures, including encryption keys and digital signatures, to ensure update integrity. This is critical in India, where cybersecurity concerns are rising with increasing vehicle connectivity. Updates also help patch vulnerabilities swiftly, protecting the vehicle from hacking attempts or data breaches.
OTA updates cannot fix physical mechanical or hardware problems. They focus on software improvements such as enhancing infotainment, navigation, engine control units, driver assistance systems, and electric vehicle battery management. For actual mechanical repairs like brakes, engine parts, or suspension, you still need to visit a service center. OTA primarily optimizes and upgrades the digital and electronic components of your car.
Most OTA updates related to improving safety features, bug fixes, and system optimizations are free during the vehicle’s warranty or service contract period. Car manufacturers usually bundle these as part of the ownership experience. However, some advanced feature-on-demand services or subscription-based connected services might incur additional charges depending on the car brand and model. Always check the terms of your specific car’s OTA policy.
If an OTA update fails—a rare event—drivers are typically alerted through the in-car system or manufacturer app. Common causes for failure include interrupted internet connections or insufficient battery charge. Indian drivers should ensure their vehicle is parked in an area with good network coverage and sufficient battery/ignition power during updates. If issues persist, contacting the manufacturer’s customer support or visiting a service center is recommended. Sometimes, updates can be retried or installed manually by technicians.
The update duration varies based on the size of the software package and the speed of the internet connection but generally ranges from a few minutes to under an hour. Most OTA updates are designed to install when the vehicle is stationary and idle, avoiding disruption during driving. Many cars allow the user to schedule updates for convenient times, such as overnight or during charging for EVs, minimizing inconvenience for Indian drivers.
OTA updates commonly cover several vehicle systems, including:
Infotainment and navigation software updates
Advanced Driver Assistance Systems (ADAS) such as lane assist, blind-spot monitoring, and emergency braking
Powertrain and engine control software for performance and fuel efficiency improvements
Electric vehicle battery management and charging optimization
Digital instrument cluster firmware
This continuous software evolution helps enhance safety, usability, and overall driving experience on Indian roads.
