Question on Garmin GNC 250XL

My question deals with the squelch on my Garmin GNC 250XL. The squelch
threshold level is not high enough. There is no adjustable squelch, only a
button that turns squelch on or off. Does anyone know how I can raise the
squelch threshold level so that the radio doesn't constantly break-in with
very weak signals from traffic WAY far away?

I hope to hear from someone,

Ron

If you remove the unit from the cage, arent there several holes
on top that reach to pots for adjusting things, including
the squelch treshold level? I recal my 300XL having that.
Just pull the unit out with the alen wrench release hole on front.
