Garmin Routable IMG Files (Australia)
The following Garmin files are an experimental set of routable Garmin maps based on the new routing version of mkgmap. I've yet to check these fully, so I have no idea how well they will work (however, reports so far from others running routable map creation seems pretty positive. That said, your mileage may vary...)
I've had some reports of junk maps (including on my own GPS). The set below were rebuilt using a newer build of the software, so they may be substantially better.
These are now being created nightly. The software used to create them is changing fairly rapidly, so hopefully there will be ongoing improvements for these maps.
