# OSM Maps
|
|
|
|
## What It Does
|
|
|
|
Integrates OpenStreetMap (OSM) data to provide speed limit information, road geometry, and other map attributes. This data powers features like Speed Limit Assist and Smart Cruise Control — Map.
|
|
|
|
## How It Works
|
|
|
|
1. Select your country (and state, if in the US)
|
|
2. Download the map data to your device
|
|
3. The map daemon processes the data and makes it available to driving features
|
|
4. Periodically check for updates to keep your map data current
|
|
|
|
## Requirements
|
|
|
|

|
|
- Internet connection for initial download and updates
|
|

## Features That Use OSM Data
|
|
|
|
- **[Speed Limit Assist](../cruise/speed-limit.md)** — Reads speed limits from map data
|
|
- **[Smart Cruise Control — Map](../cruise/scc-m.md)** — Uses road geometry for proactive speed adjustment
|
|
|

|
|
- **Delete:** Tap "Delete Maps" to remove downloaded data and free storage
