## Install Offline Maps

1. Download a compatible MUI map ZIP from Oxed's Map Tile Downloader.
2. Turn the T-Deck off, remove its microSD card, and insert the card into your computer.
3. Choose the downloaded ZIP below, enter a map name and pack ID, and wait for local validation.
4. Click Install and Enable, then choose the mounted SD-card root.
5. Safely eject the SD card, return it to the T-Deck, power it on, and open Maps.

Existing unrelated SD-card files are preserved. Map tiles are validated locally and are never uploaded.
