353: C172SP NAV Gauges Update

A couple of months ago, I mentioned there would be updates to the existing C172 Series.   Here it is the first for the Navigation set.

This update is an important one.  It not only includes graphical enhancements but also resolves more than a dozen fixes in programming and rendering.

Existing users should have received an email containing the download link in their mailboxes by now.   If not, feel free contact me directly.

This is the first wave of the C172 gauges updates.   The next will come soon.
