Over-the-air Update (OTA)
An over-the-air update installs new software in the car via a mobile connection.
What is Over-the-air Update (OTA)?
It can fix bugs, add features or update maps. Some updates require the car to be parked. Not all control units can be updated this way. Manufacturers announce the content of updates in release notes. Updates can be scheduled for a convenient time, often overnight. Some features bought later are activated through OTA.
How it works
The car downloads the update and installs it when conditions allow.
Why it matters for your car
A weak battery may stop an update; follow on-screen instructions. Some recalls are completed via OTA.
