Looking for some feedback on how the the Garmin GSD20 works for adding the color sonar to their GPS units. Is it worth buying?

I bought one last year and was pretty happy with the way it performed, but it interfered too much with my other graphs, so I pulled it off the boat. It's currently for sale on Ebay, with a transom mount transducer, and it looks like it will go cheap, if you're interested.
