Hi, I recently purchased a Del Axim pocket pc and I have been looking around your site to try and find a gps package to go with it. I am a complete newbie when it comes to GPS and the problem I seem to keep encountering is that of coverage. Firstly I should explain that my primary reason for getting a gps package is because we are planning a round the world motorcycle trip in about a years time. The software packages that I have read reviews of all seem to cover only Europe and North America and our trip is going to encompass New Zealand, Asia, Australia, South America, India, China, the list goes on. We are still planning our route, can you offer any suggestions for worldwide route planning and/or worldwide GPS packages, do they exist? Any help welcome! Great site Bye for now

Kevo,
your trip will mostly take you through terrain that is as of yet not covered by street navigation programs. But then you may not always be using streets...
So have a look at OziExplorer - it allows you to use scanned-in topographical maps of any scale, and you should be able to use your GPS - in combination with the paper maps for navigation in those countries.
There is a bit of learning involved, especially when calibrating the maps, but it is well worth the effort. _________________ Lutz

As Lutz says, you won't get street mapping or turn by turn directions where you are going, but you can get at least basic maps.
You will probably find that a lot of the time you will be reading grid references from your GPS and relating them to a paper map to create waypoints. Definately check out OziExplorer and get intimately aquainted with how the different map datums and grid references work.
As for maps, Garmin have a world map which covers major roads. There is a map viewer on their web site http://www.garmin.com/cartography/
so take a look and zoom in on an area you know well and see what it looks like.
The roads on Garmin's Worldmap can be 500 meters adrift at times and many major roads are missing. It is a vector map though and the whole world is "only" 180 Meg. It costs about 50 quid (or get it using Gnutella). 8O
It's designed for Garmin receivers "only", but you can use GPSMapEdit http://kgy.narod.ru/util/mapedit/mapedit_e.htm to import the maps and then export them in Ozi Explorer format, albeit as GIF images which are much bigger.
If there are a few of you and you want a second GPS then take a look at the Etrex Legend, they are waterproof and robust, you can also load the Worldmap vector maps directly into the Etrex's memory.
For New Zealand, there are detailed streetmaps available for Garmin units, once again you can export them into Ozi format using GPSMapEdit. Have a look at http://www.gpsriders.net/nz_mapping.html These maps are from NZ land and survey and are VERY, VERY detailed, virtually every NZ street is there.
I am going to NZ in a few weeks (sadly, without my bike!) but I will let you know how accurate the maps are. :D

If there is no mapping, what happens to the GPS mapping. Can I still add POIs without an actual map? In other words if I add something as POI coordinates, will it still show even thought there is no mapping info?

If you are traveling somewhere that you don't have streetmaps for then depending on your mapping software you may get a blank page or it may not work at all.
You certainly don't necessarily need a map to add POIs or waypoints and navigate between them though. Indeed, some low end hand held GPS units (eg Garmin) don't have any maps at all! On the pocket PC you can get programs like Fugawi and OziExplorer which will allow you to communicate with your GPS and create waypoints and routes manually.
What you have to do is look at a paper map and read grid references (eg Ordnance Survey grid references or lat/long in degrees) and use these to create waypoints for your start point, destination and intermediate points.
The GPS software can then display a compass arrow showing the direction and distance to travel to the next intersection on the route (marked as an intermediate waypoint using the grid reference from your map). When you get there, it can give you a turn instruction and display a new distance and heading to follow to the next waypoint and so on.
One of my favourite tricks with the GPS is to mark the position of the car when parking in a large car park (eg the long term parking at an airport) and use the compass heading to find my way back to the waypoint I set when I parked the car! 8)
