1. Is a permanent Internet connection required to use NaviComputer?

NO. NaviComputer is actually comprised of two applications: NaviMapper, which is installed on your PC to download maps, and NaviComputer App, which resides on your device (which also has the ability to download maps directly off a data connection)
Your device requires an Internet connection only if you wish to download the maps directly onto your device. NaviMapper which is an application included with NaviComputer, can download the maps from the Internet to your PC. They can then be transferred and stored anywhere on your device. Once the maps are downloaded, NaviMapper no longer requires an Internet connection.

2. Can maps be viewed offline?

YES, as long as they have been stored for viewing.

3. From where can I obtain maps?

Maps can be obtained from many free map sources. One good source is OpenStreetMaps. Maps are saved as single, easy to handle, space saving (.nmap) files.
Be aware that certain map sources will not allow users to cache maps, such as Goggle and Yahoo. The practice is illegal and NaviComputer does not condone such action by users.

4. How long does it take to download maps?

This depends on the speed of your Internet connection and the speed of the server from where the map is downloaded. The higher zoom levels are comprised of many more tiles (pieces), and take the longest to download.

5. Is NaviComputer able to do point to point navigation?

Only if a track is used that has been saved or imported to Navi. Navi is a map/GPS software for off-road navigation and track recording. It is very useful for outdoor/adventure sports, hiking, biking and so forth. However, it can be used to follow a track displayed onto the screen map. Navi does not have any "directional guidance" or route planning functions.
Navi is in its' early stages of development and with each version, more features will be added, but it is not intended to be a full navigational capable GPS application such as Garmin, Tom-Tom and others.

6. What are the system requirements for NaviComputer?

PC:
Windows XP, Vista and Windows 7
Net Framework 3.5
Device:
NetCompactFramework 3.5
Windows Mobile 6.1 or 6.5 operating system
Touch display
GPS receiver (internal or external)

7. Does NaviComputer support W/QVGA?

YES. WVGA, VGA, QWVGA or QVGA are supported.
This was added in version 0.6

8. How do I install NaviComputer application?

1. Download the NaviComputer file to your PC and execute the file marked "Setup". This installs NaviMapper to your PC.
2. If you have Active Sync running and your device connected, NaviComputer will be automatically installed to your device. Otherwise you will find the cab file for manual installation in the NaviComputer Program folder.

9. Can NaviComputer store and display tracks?

YES, it can. It can also use tracks imported in the standard GPX format. Track-points are not added by Navi unless the distance between the new track point and the preceding track point is 3 meters or greater. This prevents the size of the track file from increasing when you are not moving.

10. What is a GPX file and how is it used with NaviComputer?

GPX is a shortened acronym for GPS eXchange Format). GPX is a data format for exchanging GPS data between programs, or for sharing GPS data with other sources. GPX is different from other data files which can only be understood by the programs that created them, in that GPX files contain a description of what's inside them, a sort of "benchmark" if you will, allowing anyone to create a program that can read the data contained in the file.

11. Can NaviComputer import and use tracks from other sources/GPS?

YES. NaviComputer is capable of importing tracks, routes and waypoints from GPX files. GPX files are stored under Logs in the Navi Directory by default.

12. Does NaviComputer have the capability to display user waypoints?

YES. Waypoints are supported as of NaviComputer Version 0.90

13. I've downloaded maps and they are in the Map folder but NaviComputer does not show them?

Most often this is the result of not having your desired location in the center of the map screen.
If you downloaded the map set correctly and placed it into the Map folder (default location) in NaviComputer, you should be able to view any map set, provided that the location to be viewed has been moved under the center point of the map screen. If the area you wish to view is greatly magnified (larger zoom levels 10 and up-smallest area), it is difficult to be right over the center of that area in the default zooms (1, 2 and 3), and Navi may not "see" the map. The smaller the zoom levels (least magnification, below 6 - greater area) included in your map set, the better chance you have for Navi to load the map. Your trying to find the head of a pin on a world map!
REMEMBER:
The program will always switch automatically to the map, which fits the actual screen's area, and zoom level.
NOTE:
Since version 0.90 it is also possible to select and show a specific map manually, so it is not necessary to place the location in the center of the map screen and manually zoom in/out. This function is accessible in the contextmenu of the Offline Maps list.

14. Can I switch off the display while recording my gps track in order to save battery power?

You can simply put your device to standby mode. NaviComputer will keep gps powered on and track your route.

15. I tried to import a gpx file but it only says "GPX file not supported" or even freezes the application. What is wrong?

NaviComputer basically is capable of importing all kinds of GPX files - tracks, routes and waypoints/POI. Although GPX is a standardized file format, some GPX tools create non-standard 'conform' files and NaviComputer may have difficulties to import them. In this case, it may be helpful to open and save the file with another application, and then import them to NaviComputer Log file for use. I can highly recommend the online converter at www.gpsies.com for this purpose.

16. How can I modify the "MapSources.xml" file to add "map sources" from which to download?

In this example, Freemap Slavakia maps will be added to the xml file.
You will find the MapSources.xml file in the root of its' directory in both applications. They are the same, and each must be modified in the same manner.
Copy and paste the file into Notepad or similar editor. Make the appropriate changes.
The name you use as the mapsource ID can be what you choose. It will be the name displayed when you view the Options/Map on NaviComputer, or in the drop down on NaviMapper.
The following attributes must be entered within a "MapSource"-Tag in the xml:
Copyright(optional): The copyright info.
MinZoom: The lowest available zoomlevel of the map source.
MaxZoom: The highest available zoomlevel of the map source.
TileUrl: The url from where the map tiles are loaded. The placeholder %z, %x and %y are used to specify the tile coordinates. In addition the placeholder %k can be used for map servers which are using the quadkey tile identifier. See here for more infromation about the tile system.
It is possible to add more than one TileUrl attribute. This way, parallel download from multiple servers is possible.
Note: Due to xml formatting, the character "&" (often used in php urls) must be replaced with "&"
Save the file, and transfer the file back into NaviComputer and NaviMapper directories.

---------------------------------------------------------------------------

Tip: Finding out the tile url of an online map source is really easy. Simply browse the map online and use a tool like the firefox addon HttpFox to see from which url the tiles are loaded.
Some available additional map sources are listed in our Blog post.

17. How do I choose different map sources that I have downloaded

If you have only one map type of the current location and zoom level available, the program will automatically switch to this map. If you have more than one map type available (for example you downloaded Street and Satellite view of the same area) you can switch between the types in the Context Menu under Map option.

18. How do I set the GPS settings?

You don't need to. This application is using windows mobile intermediate GPS driver. It will automatically detect the settings from the windows mobile settings menu. So if GPS does not work, please check GPS settings menu on the windows mobile device first.
If you are using an external GPS, please refer to the Blog post HowTo:Setting Up External GPS.

19. The application does not start. I get an error message.

Please make sure you have the latest .NET Framework 3.5 re-distributable is installed on your PC and, that both PC and device comply with the additional requirements.

20. Can the downloaded maps and zoom levels be split into more than one file?

YES. You can download zoom levels, as you need them. It is best to put them all into one file, but NaviComputer will find the map it needs and load it onto the screen as long as all the zoom levels are in the same folder on the device, and the map file location has been set in the Options menu.

21. Do the zoom levels need to be continuous for Navi to read them correctly?

No, they don't need to be continuous.

22. Can a map file be split or modified once it is downloaded? Combined?

NO. You CAN create more than one file for a map set, but the individual files cannot be divided, changed or combined once they have been downloaded.

23. What is 2x Zoom?

This will digitally increase the map with factor 2.

24. How do I access the Context Menu? What do the Options mean?

The following additional map features can accessed via the context menu, which will pop up when you tap and hold anywhere on the map screen:
1. Center GPS Position: When this option is checked, the map will be automatically scrolled so that your position is always in center of the map. As soon as you manually scroll the map, this option will get unchecked automatically. Please note that you can check this option only when you have a GPS fix.
2. 2 x Zoom: This will digitally increase the map with factor 2.
3. Map: Whenever there is more than one map source available of the actual location and zoom level, you may switch between different map types here. (e.g. switch between OpenStreetMap and OpenCycleMap)
4. Add POI... Adds a Point Of Interest at the location where the map has been tapped.
5. Online Mode: This will toggle between Online and Offline map mode.
6. Download Map… A dialog will be opened to download map content for use in offline mode. The map sector to be downloaded is the actual visible sector in map view. Zoom levels and filename can be chosen in the download dialog. Downloaded. nmap files will be stored in you map directory (defined in options). Please note that this menu item is enabled only in online mode.
