Offline maps
Offline maps you can actually manage.
Download the map areas you need before you leave signal, then see what is on the device, what is queued, what needs updating, and what has been verified.

Choose the right map areas
Prepare the maps that match the trip and the device you will carry, rather than assuming every map file follows you automatically.
- Choose whole maps or selected areas.
- Download on the device that will use the map.
Check download status
See whether map areas are queued, downloading, stored locally, or need attention before you leave reliable signal.
- Use visible status instead of guesswork.
- Review updates before a trip.
Review storage and verification
Offline map files can be large, so OMN4 gives you places to review storage and verify saved data.
- See what is stored locally.
- Verify saved map areas before relying on them.
Manage each device deliberately
Offline downloads are managed per phone, tablet, or desktop. That is a feature of the workflow, not a sync failure.
- Choose what each device keeps offline.
- Use help docs for step-by-step operations.
Help and detail
