I agree. It would make it much easier to create custom maps and also share the custom maps with what the garmin community have been doing.

Garmin's instructions detail a simple 5-step process for creating a Garmin Custom Map. The steps involved to creating a Custom Map are:
1. Find a JPEG image of the map you would like use on your GPS.
2. Calibrate the image using Google Earth using Google Earth's ground overlay feature.
3. Save the ground overlay as a KMZ file to your Garmin GPS.
4. Enable the custom map on your GPS. CM3.)
