Here's what's in the panel:
Note that I have hardwired connections for both a Garmin 496 and 696, providing power, audio to the audio panel, and accepting data from the XRX traffic unit to either GPS.
All engine instruments are stock, there is a single channel analog EGT. The only unusual instrument is a coguardian 553 clock, which is an great instrument, it simultaneously displays local time and zulu time and can be toggled to show the following:
Flight time (automatically counts)
Stop Watch
Inside and Outside Temp in both F and C
Battery Voltage
Cabin Altitude (provides a brief warning when you climb above 10,000 feet)
Density Altitude
Carbon Monoxide Level in parts per million
I just installed the coguardian last month, it cost $700,is impressive and easy to use.
In May I upgraded the avionics stack and had the entire stack rewired. This included: Radiorax for $400 (these are faa/pma approved u channel tracks that make it super easy to install/uninstall and adjust components in the avionics stack.)
http://www.radiorax.com The Radiorax are such a solid mounting point that the radios no longer require additional support brackets on the back side. Note the Radiorax are the blue stripes on the side of the radios in the photos
We installed an avionics cooling fan, and disconnected the external air duct that has a tendency to draw rain and other contaminants into the avionics.
Anyway, here's what is in the stack from the top:
1. A Bendix/King Colormap III. This is a portable VFR only GPS that has all the functions of a KMD 150 panel mount GPS, including terrain database. It uses the King panel mount kit, and can be removed in seconds. I have owned this Colormap III for several years, and had it serviced and updated last year. I had used it as a portable all along and decided I liked it well enough to panel mount it. It could be used to provide GPS data to a fuel flow instrument, which I intend to install in the future.
2. A new PS engineering 8000B audio panel. I have one of these in my 150, and like it so much I got one for the Cardinal. It is stereo, and has the capability of providing stereo entertainment from two sources simultaneously. This allows the back seat passengers to listen to their own music separate from the front seats, I have it set up so the co-pilot can choose to listen to either the front seat or back seat entertainment output.
3. An Garmin SL-40 comm (new)
4. A Bendix King KX125 Navcom, this has a built in CDI but is also connected to a King 209 external CDI, which is also connected to a King glideslope receiver.
5. A King KN-64 DME
6. A Narco AT165 transponder (new) Nice unit, all digital and solid state, displays the altitude that the encoder is squawking, has an automatic flight timer, manual timers and can optionally be used as an altitude reminder.
All new breaker panel for the avionics stack, and breakers for portable avionics, including three portable GPS units, and a XRX traffic alerter.
I also installed a mini switch panel that allows the traffic info to be routed to any of the three portable GPS units, and the entertainment channels from various sources etc.
