Simrad WP Belt
The belt is easily accessed by removing a few screws from the plastic weather cover. However, I wanted to replace mine under warranty and Simrad said that the belt must be installed by a factory technician. Hence, I bought the belt and installed it myself rather than having to remove the entire unit and send it to the factory. My belt failed underway during a long cruise. I had some strong (80lb.) fishing line so I sewed it back together. As an aside, you can extend the life of the belt immeasurably if you swith the unit to Standby when one of those God Awful Bayliners goes by.
