I'm new to OSM, having recently replaced my 12 year old Magellan GPS with a Garmin Etrex Legend CX.

I've been following with some interest the discussion about roundabouts and how they are mapped. I have downloaded the OSM maps into my Etrex, but as far as I was aware, the OSM maps were not routable. They certainly aren't on my Etrex. Any attempt to "GoTo" a waypoint or a POI gives an error message "No roads near starting point".

Now I know that this is not a fault of the Etrex. I have a card which I bought for $45 on eBay, which is routable, and will give turn by turn directions to a location. It's not much of a map, though. Streets aren't accurate, and many streets appear twice. And the nearest ATM to a SW Sydney suburb was the Westpac bank in Ballina. (What would you expect for a $45 card?)

But your discussion about roundabouts tells me that OSM maps can be routable, so I must be doing something wrong when I load them. I am downloading the individual .IMG files from the OSM Australia website (http://www.osmaustralia.org/index.php), and I have used a utility called MapsetToolkit to make the OSM maps appear in the Garmin MapSource program. This lets me simply select the tiles that I want, and transfer them to the Etrex via MapSource. It also lets me add Contours Australia maps, so that my OSM maps have contour lines. Works well, but the maps aren't routable.

I thought of trying the IMG2GPS program that is recommended on the OSM Australia website, but it doesn't seem to be available any more. All the links go to an expired domain name.

Does  anyone have any suggestions?
