What map system does Subaru use?
Map data provider
Subaru’s navigation is powered by a dedicated map database supplied by TomTom, a long-standing partner for automotive navigation systems. This data underpins the road network, POIs, and routing logic used by Subaru’s infotainment systems.
- TomTom map data powers Subaru's in-car navigation and its road network, points of interest, and routing rules.
- Live traffic and incident data are integrated from TomTom's traffic services within the system.
- Regional availability and features can vary by model and market, so always check your owner's manual for specifics.
In short, TomTom serves as the backbone for Subaru’s map data, with updates managed through official channels.
Regional considerations
Most Subaru models worldwide rely on TomTom as the base map provider, though regional variations and localized data practices may apply. For model-specific details, consult Subaru’s regional support resources or your dealer.
Updating maps
Map updates are delivered through Subaru’s official channels and may use different methods depending on the model year and hardware in your vehicle.
- USB drive updates: Download the map update package from Subaru’s support portals, transfer it to a USB drive, and install via the vehicle’s head unit.
- SD card updates: Some head units use an SD card; copy the update files to the card and insert it into the navigator.
- Service-center updates: Certain models can have updates performed at a Subaru dealership or authorized service center.
Before starting an update, ensure your vehicle has a stable power source and follow the official instructions to avoid data loss or navigation issues.
Summary
Subaru’s built-in navigation uses TomTom map data, with updates distributed through official Subaru channels and, depending on the model, via USB/SD card or dealership service. While TomTom is the primary source in many markets, regional differences can exist, so always verify with your owner's manual or local Subaru support for your exact model.
