Cambridge 20 GPS/NAV freshly calibrated 8/12/09 with software version
6.0 along with an LNAV with 57mm (small) variometer for $1100. This is
an IGC approved system that is a perfect entry-level low-cost system
that doesn't need a PDA to operate. Works perfectly and the only
reason I am selling it is that I use a PDA and am upgrading. Contact
me for questions.
