I compile my own maps for the Garmin Edge device, the data is updated about every 30 days. I download the raw data from geofabrik and create them using a custom TYP file that shows a lot of details and color when compared to what you get from Garmin or the standard TYP from openstreetmap.nl
My maps are located here: http://edgemapcreator.mooo.com/Maps/
