Volvo has announced its biggest ever over-the-air (OTA) software update with the global rollout of its new user interface, ‘Volvo Car UX’, which will be free of charge for vehicles dating back to 2020.

In what it claims is one of the largest automotive software updates in history, the company said the new update will apply to more than 2.5 million Volvo vehicles in 85 countries, including around 33,000 in Australia.

Volvo said the update “prepares cars for an optimal conversational AI [artificial intelligence] experience with Google Gemini, which is set to come to the same eligible cars this [European] spring [April-June 2026].”

Vehicles made from 2020 onwards and using Google Built-in will be given the upgraded Volvo Car UX (user experience), which is based on the Android Automotive operating system.

Google Built-in was first seen in the 2020 Volvo XC40 small SUV, introducing functions including Google Assistant and Google Maps navigation, as well as connectivity with smart home devices.

In Australia, the roll-out saw Google Built-in spread across all Volvos sold from 2020, before spanning the Swedish auto brand’s entire lineup from the 2023 model year.

In a statement, the Geely-owned automaker said its new user interface software “takes fewer taps or clicks for customers to reach the most-used features”.

This includes faster access to maps, media and phone functions, which have been positioned on the home screen. Volvo says this means drivers won’t have to exit Google Maps to change the music, for example.
