The single display G3X panel shown below is at the other end of the spectrum from the great 3 display panel that Matt posted, but it shows what you can do in an aircraft with a small instrument panel like the Longez.
The most important engine gauges are shown at the top of the PFD. There is a separate engine page that shows the less critical gauges that can be selected to the bottom of the PFD.
The XM radio and audio alert connections from the GDU375 are tied into the GMA240 audio panel which is great for this because it has a dedicated music volume knob and a quick access Music on/off button.
Separate GPS and XM antennas are mounted inside the aircraft under the access hatch you see in the linked picture of the aircraft. Since the XM receiver and GPS are built into the GDU375 display, the antennas are very small.
The AHRS/Air Data/engine interface is mounted forward of the instrument panel just aft of the canard on a bulkhead. The magnetometer is mounted in one of the wing strakes.
Since the Longez doesn't have the heat generator up front, you have more flexibility in mounting the OAT probe. This one is mounted in the nose gear retract mechanism area (not sticking out to cause drag). The air temp in this area is always the same as outside air.
The last picture was taken this weekend just before the first flight. This was the first flight of a G3X system in a homebuilt aircraft.
