Have had nothing but issues since first installed (wired to my 5215) a couple years ago. Most recent issue is that
wind speed does not
record properly--shows
wind at 100 to 120 MPH. Other things like wind direction works fine.
Garmin service says one more time: send the unit back and pay us $359 and they'll send a new one--have done that before and new one works for a while.
Does anyone else have this wild speed read-out problem. And do you have any suggestion for how to trouble shoot it--besides paying
Garmin another $350?
Thanks much
Randall
