LMLers,
I've just upgraded to a GNS 480 navigator and have no room left in my little
panel for the GX60 that has served me so well for my first 300 hours. I am
offering this unit for sale to the LML community for a few days before I put
it on eBay. The GX60 is an IFR Approach Certified (TSO-C129A) GPS / COM.
The COM in this unit is the same communications radio that is inside the
famed SL30.
This unit includes:
* GX60 unit (with new internal lithium battery installed in June 2007)
* Mounting tray
* Installation hardware
* A-33 GPS antenna
* Annunciator Control Unit (ACU) which is required for the approach
certification and allows you to switch your CDI between the GPS or a NAV
signal (this was an extra $695 when I got the unit)
* Installation manuals
* Operator's manual and quick reference guide
* Data card with July 2007 data loaded in it
* This unit can be driven with 10 - 40VDC
I'll guarantee that this unit is in excellent working condition when you
receive it.
Price: $2700 (I saw these used - and beat up - for $2600 for just the radio
at OSH this year)
I've attached a couple photos of my system as well as the factory specs
below.

Overview
The GX60 is an advanced navigation and communication solution in a single
two inch package. No other GPS/Comm can deliver the transmit power, the high
definition moving map display, the TSO certified navigation and the
communication performance of the GX60. The Apollo GX60 is an approach
certified GPS receiver loaded with features including a high definition
moving map display on a large sun light viewable screen. The aircraft's
position relative to airports, runways, VOR's, NDB's, intersections, and
SUA's can be easily viewed on the large moving map display. Operation is
streamlined and pilot workload reduced through the use of Smart Keys.
Airspace's and navaids can be added or deleted from the map with a single
press of a button. The GX60 is TSO-C129a Class A1 approved for IFR non-
precision approach operation.
