A little Garmin mapping info
Mapsource Metroguide Australia totals 48MB and Mapsource City Navigator Australia is about 44MB(?) so you should be able to load all of both products onto a 128MB card.
You need to select all the segments that you want to load in one session and download them together.
If you are doing it via the serial data cable then you will also need an external power source for the SPIII as the load will take several hours.
Mapsource has a hierachy in the maps it displays and if you have both CNA and MGA loaded for the same area it will only display CNA.
To disable CNA, select map page,, MAPSOURCE INFO,,, select what you wait then, thenout
This may be a little off as I don't have the unit in front of me.
If you are thinking of buying a mapping GPSR and do not need turn by turn 'auto-routing' then you may wish to consider the Garmin GPSmap176 or 176C instead with Metroguide and a data card.
MGA has identical metropolitain area mapping to CNA and, as others have noted, much better rural mapping. MGA supports all the same address and POI find functions and the straight line goto is still very useful (even in the city.
A GPSmap 176/176C is also a fair bit cheaper.
