Hi Mijanou,

It sounds like you have not uploaded the mapset to your Garmin device.
To do this connect your GPS through the USB cable and then use the MAP Select on Mapsource to select al of the maps that you want to be able to see on your GPS. Then you just need to click on the icon that shows a little GOS device with an arrow pointing into it. This will upload all of the maps you have selected into your device.
With T4A you will have no problem fitting the whole of Australia into the memory card of a MAP60CSx.
I hae exactly the same GPS with Metroguide, Bluecharts, T4A, T4A Pro, and now Shonkymaps all installed on the card.
I would recommend you do a search for Shonkymaps and install them. I rarely use anything else now except when I am in my yacht using the Bluecharts.
Shonkymaps are free and can be downloaded from a couple of different sources but I think Shonky has now set up a small site specifically for downloading Shonkymaps. The file size is about 330Mb if that is an issue.

I hope this helps.

Brett

If it's loaded onto your Garmin (as you say) then you probably haven't selected it as the map to view.
