Magellan - Meridian GPS

The Discover Aus software enables you to up load up to 4 regions into the ram of the GPS or the whole of Oz onto 264 Mb card. It won't allow you to change the basmap over to the Australian basemap however, so as you zoom out you will go from the high detail of the Discover Aus region you are using, to useless low resolution of the world basemap. There are ways to replace the US basemap with the Australian basemap, but there are copyright issues. I migrated it from my Map 330 to a US sourced Sportrak Color succesfully. An intermediate solution is to use Magellans Mapsend Worldwide Basemap software and upload a somewhat better basemap of Oz, but it still is nowhere near the resolution of the 8 Mb Aust basemap. I believe Magellan will change the basemap for you but it'll cost you about $300.

Tom,

Have a Platinum and have as Bob suggests loaded Streets and Tracks loaded onto a 256 Mg card covering all of Australia. I also use a computer at times for moving map display. The card was on Ebay too at $109 landed but learning to use it was interesting too as I also had to update the firmware in the Meridian to handle the updated card.

With some versions of Meridian basemaps of Australia there are some major inaccuracies, like Cairns inland from Brisbane. Streets and Tracks loaded, overcomes some of those problems with major benefits like naming most of the roads you are about to cross as well as the one you are on. It is not commonly said but Streets and Tracks will handle the moving map on your computer too and help to find streets you are not familiar with.
