Check out Simrad WP
Bill:Check out the WP100 or WP300. They are a breeze to install and have better specs too. Everything mounts on the wheel. Just run the wire down the pedestal and wire the thing up. You are ready to go. We have had ours for two years now and could not be more pleased with the unit.If you want to hear about all the complaints about the Autohelm 4000's just check out the archives.
