have been following this threat with interest......... just acquired an X5 with P7 control head after having gone through two ST2000+'s in three years with one constantly in the shop for repairs. I suspect the vibration from the yanmar destroys the built-in ST2000+ fluxgate compass over time. I am hoping to have better luck with the new system and may even consider mounting the course computer on an anti vibration pad of some sort.
