If you have an old Serial Cable lying around i.e. from a mouse, just grab an ePlug from your local supplier and away you go. One Garmin cable for the price of peanuts.
Search for ePlugs on google.com to find a ePlug supplier near you.
I made mine up in about 10mins and saved $80 (aus) in the process.
