Dude! Where Are We??? -- Off-Roadin' With Fugawi Global Navigator 3.3.1

Unfortunately, installing maps to the PPC is a little cumbersome, since, again, they must be installed from the PC-based program. Northstar, the vendor/manufacturer in Canada, provides complete coverage of Canada using NRC maps at 1:250,000 (for an entire province) and 1:50,000 for specific sections. 1:50,000 is OK for longer hikes or bike rides where you're covering tens of miles in a day, but it would be better to have something like 1:20,000 for more in-depth detail at a local level.
To transfer a map to the PPC, you need to bring it up on the PC, select an area to be transferred, zoom into an portion of the selected area to set the level of detail desired, then 'prepare' the map for the PDA. Preparation of a map basically consists of rasterizing the selected area of the map (i.e. creating a bitmap image) at the detail shown by the current zoom level. Depending upon the size of area selected and the zoom level, this preparation can take 5 to 10 minutes. It is possible to rasterize the entire map, but this would take longer and could require considerable storage space.
The PC version of Fugawi Global Navigator also supports overlaying of maps, such as placing the Street map over the topographic, to produce a pretty complete view of the terrain around the streets. Unfortunately, the PDA preparation routine only works with the base map selected, so you only get the topographic in the final PDA-ready image – not the streets.
Once the preparation is complete, you then select another function in the PC version to 'manage' the maps located on the PPC. This includes transferring from PC to PPC, deleting from the PPC main memory or storage cards, etc. Prepared maps are found on the 'Exported Maps' tab – which is not well explained in the documentation.

Transfer occurs through the ActiveSync connection and, depending on the size of the map section, can take 15 to 20 minutes (for large sections).
