The tech person may have ment a heading sensor rather than a wind insturment. Can't imagine you would need a wind insturment. I notice that a heading reading was not available on my Garmin 3006 when I first got it. They do give you a compass display from which you can geat the heading degrees though so I have no idea why they elminated the heading degree reading. I don't really need / use the VMG function, not a racer.
Rather than cutting a big hole in the bulkhead why not mount on a piece of teak with a small hole for the wires?
