This Navajo, equipped with over 150 lbs. of outdated
    avionics, had been modified a number of times over the years.  It was in need of some
    good modern IFR avionics & instruments to navigate the east coast's airspace system.If
    you're already completely overhauling the instruments & avionics in an aircraft that
    you fly 100 hours a month you might as well make it the way you want it.  So we
    removed the entire instrument panel and cut new panes for pilot, co-pilot, and avionics
    stack.
    The new panels were painted an labeled appropriately.
    The pilot got a Sandel 3308
    EHSI.  The co-pilot got a King KCS-55 HSI.  The new avionics stack consists
    of a Garmin GMA-340 audio panel with marker
    beacon, 2 Garmin GNS-430 GPS / Com / Vor /
    ILS transceivers, and 2 Garmin GTX-327
    transponders.
    Why 2 Transponders?  Just try getting out of any large northeastern airport
    without a functioning transponder.  When you use your aircraft for business you can't
    be stuck on the ground trying to get the field's only avionics shop to fix it Friday at
    9pm.
    Gone are the old post lights, in come NuLites on
    each non-internally lighted instrument.
    To enhance passenger comfort we installed a CD player & changer in this aircraft.
      The crew can even listen in and not miss radio calls using the Garmin GMA-340's
    music input.
    A power converter was also installed to provide 12 Volt power outlets in the cabin for
    cell phone recharging and laptop use.
