I will be installing a new Raymarine smart pilot X-5 wheel as a replacement for my old ST4000 that has given up , as parts are hard to find and I will be able to interface with my Garmin. any opinions good or bad ??? I know that the new X-5 is a direct replacement and I have read a few comments, but as they say more is better. sailor tested is the only true test of a product thanks to all for your imput======SEABEE1
