First steps and uses

Assumed you have downloaded and installed ZANavi, just run it once. It will show an overall map of the world. You now can zoom to higher resolution yet after a short while the map disappears (white screen). This is because no detailed map is loaded. Just hit the menu button to show the menu, choose entry “… more” and then “Download maps”.

Download maps

The list of downloadable maps is rather large. To scroll to the wished map wipe once down, then a scroll button appears which allows scrolling much faster. Select the country you wish to download and the download will start.

First an output file will be created, afterwards the download may need quite some time. If the download needs too long for your liking, hitting the back button will cancel it immediately without confirmation.

It may happen that no download is done because the server might be too busy. Just try it another time.

Zooming in (+) and out (-)

After downloading one or more maps it will be used and shown when you zoom in. Be carefully you zoom within the borders of your downloaded maps, else you might soon get a white screen. Zooming or moving of the map might take a while, therefore a “Wait…” box is shown. Just be patient, the map will finally be shown. The zooming is always centered at the current position.

Once a while there’s yet another white screen shown without any map items. This is due the fact that in some areas (mountains, sea, deserts, etc) there aren’t many map features, sometimes too few or too less important to show. Just zoom out until there’s anything shown. To correct this go to OSM (Open Street Map) and help adding items to the map. Create tracks when navigating and upload them to OSM so either you or others might create new ways or correct existing ways.

Pinning to the current position

To show the current location press the red pin on the right side down. If the GPS or GSM/3g/Wireless position has been gotten, the map will be slide to this position. The current position is shown as green circle ring when you aren’t moving. When you move around a green arrow is shown and the map is slide along. Be carefully with the orientation of the map, north is where’s compass (in the right down corner) points and not always on the top.

When the map is pinned you can’t slide the map, it will just positioned back to the current position. Simply release the red pin.

Selecting a target destination

When you want to select a location on the map as your destination, touch and hold this position until a balloon “drive here” appears. Touch this balloon then routing to this location will be computed. After a short while the route is shown as a green line along the found route. Of course it will also immediately switch to the start location. The target position will be included into the list of targets under the name “Point on Screen”.

If you want to stop the routing go into the menu and choose “Stop navigation”.

Searching a target destination

To search a target go into the menu and choose “Address search (offline)” or “Address search (online)”. A window is shown with a destination field and some more fields. Tip the destination field to bring up the keyboard. Most probably set the “partial match” box to produce more results. If any result is shown touch one, if the right one touch “Use as destination” else touch “back”. If you’ve chosen a target, the routing will start and slide the map to the starting position.

In case you’d like to further fine tune the target destination do the following steps: Unpin the position (don’t stop the navigation), zoom to route, move the target flag to the position normally occupied by the GPS and zoom to the level you need to set the target manually (see “Selecting a target destination” above).

Selecting previous targets

When a previos target should be used again, go into den menu, choose “… more” and then “Previous destination”. Touch any of the available entries to select a target.

Creating new tracks

Tracking a none existent route is an essential part of using OpenStreetMap maps. for tracking ways use:

Volume of Spoken Directions

Use the Volume up/down buttons of your phone to turn the Announcer voice louder/softer. Of course it will only speak any announcements if navigating a route.


As speech (text to speech) the installed voice on your android device is used. usually this is “pico” TTS, which is free and included on most devices. if you want the speech to sound better you can install one of the following TTS systems (some are not FREE!)



The menu changes according to the routing mode (on/off).

Menu in routing mode off

  • Address search (online): Searches a destination online via Google (needs internet).
  • Address search (offline): Searches a destination offline (see “Searching a target destination” above).
  • Exit ZANavi: Ends the program, it doesn’t use CPU power anymore.
  • Toggle POI: Shows or hides certain POIs (point of interests).
  • Settings: Brings up the Setting display (see section “Settings”).
  • … more: Brings up more commands (see the following):
  • Announcer off/on: Disables/enables the speaking of routing information.
  • Recent destinations: Shows the last used destinations. Touch any of these destinations as your next destination.
  • Download maps: Brings up the download maps display (see “Download maps” above).
  • Delete maps: Brings up the delete maps display. Be carefully when selecting a map, it will be deleted immediately without confirmation!

Menu in routing mode on

  • Address search (online): Ditto above.
  • Address search (offline): Ditto above.
  • Stop navigation: Ends the routing and removes the target destination. Select previous destination to start routing again.
  • Zoom to route: Changes zoom level so the full route is displayed.
  • Exit ZANavi: Ditto above.
  • … more: Brings up more commands (see the following):
  • Toggle POI: Ditto above.
  • Setting: Ditto above.
  • Announcer off/on: Ditto above.
  • Recent destinations: Ditto above.
  • Download maps: Ditto above.
  • Delete maps: Ditto above.


The settings allow configuring the programm to your liking.

  • GSM/3g/Wireless: Use GSM/3g/Wireless networks for positioning (needs internet). You can also set it if your phone has GPS. GPS will be preferred, if no GPS lock is found then 3g/Wireless will be used for position.
  • aGPS: Use assisted GPS (need internet).
  • Follow: Center on GPS, activate this for compass heading to work (same as the red pin).
  • Lock on Roads: Lock Vehicle on nearest Road. Turn this off if you are walking or travelling off road.
  • Vehicle in center: Show vehicle in center of the display instead of in the lower half.
  • Sat status: Show the status of the GPS satellites. Empty means no satellites, yellow mean there are but not enough signal, green means GPS position found.
  • Compass: Get direction from the compass (needs lot of CPU!).
  • Compass always: Get current heading from compass even at higher speeds.
  • Fast compass: Turns display much smoother (Warning: WILL EAT ALL your CPU!).
  • Imperial: Use Imperial units (miles) instead of metric units.
  • Prefer Highways: Prefer highways (motorways) for routing. this is the default routing mode.

If you turn this off then ZANavi will also use smaller roads for long distant routing, which needs more memory!

  • 3D: Show map in 3D (beta).
  • Zoom level: Saves last used zoom level.
  • Anti Alias: Draw with anti alias, map is nicer but drawing is slower.
  • One-Way Arrows: Show arrows on one-way streets (beta).
  • Debug Msg: Shows debug messages (debug).
  • Language: Select language for spoken directions and for the ZANavi interface (menus, settings) instead of the default one (needs a restart!).
  • ZANavi Version: Shows current version info. Use this info if you want to report a problem or submit a wish.
