S-Nav Recalibration?

I may be in the need for an s-nav calibration. For the last few flights i've been wondering why the s-nav keeps showing 50+kt headwinds no matter which way I go. So I finally read the fine manual, and tried to adjust the airspeed offset in the box. Even at full -99 it till showed an airspeed of 50 knots. Is there something I can do, or does the box have to go to the shop to be adjusted?

Does Clear Nav now work on old cambrige prodicts?

Thanks

Peter

Hi Peter,

Yes. Gary Kammerer at ClearNav can probably fix it. You can reach him
through the web site at www.clearnav.net.
