EGNOS Link
I cant hit a board in the daylight so does that mean I get -ve points - so it may happen sooner
The original G1000 was NOT WAAS certified (it is the certification that is important) - but all NEW models are certified. When you mention EGNOS to GARMIN they tend to look blankly - initially they told me it wont work. As an electronic/software eng. I know this to be somewhat inaccurate. However until they can "certify" it I suspect the answer will be no. They wont even let you upload waypoints because it might interfere with the integrity of the system

I havent checked to see if the new one detects the EGNOS system - last I heard it didnt but I dont think EGNOS had enabled the "Im Ok" signals yet.
I would thoroughly recommend the G1000. It is modular so should be upgradeable (mine has been updated numerous times). The G1000 proved its worth to me very recently. If your lucky enough then go for the new one with full VNAV fully integrated autopilot. Otherwise it is still a great system.
