Sandy, if your CNX-80 now shows "GNS-480" in the splash screen,
then I'm jealous. I even still have the same old Apollo CNX-80 bezel.
I was hoping it would come back re-branded, but no such luck.

The earlier version SUSPended at the FAF because the FAA insisted.
It's better now.

Do you still keep your airplane at Don Scott?

John-
I've had a CNX-80 since July, and just got it back with the V 2.0=20
software, which turns it into a GNS-480 with VNAV. There is no =

with the other Garmins:
1. Yes, VNAV is huge... I can do LNAV/VNAV approaches to tons of =

and LPV down to near ILS minimums to a few, with more added every =
month.
2. GNS-480 updates 5X/second vs once/sec for other GPS's. Once a =
second=20
doesn't hack it on VNAV approaches -- an aircraft can move 20' =

in a second before you get any indication... at 5fps you move only 4'.
Also, 5X/sec is fast enough that you can keep the plane upright if you =

all your gyros - 1/sec is NOT.
3. Airways... they are NOT gone in the NE. From New Haven, Teteboro,=20
KSLK, etc., many times ATC has thrown FRC's with airways at me shortly =

after take-off. With the GNS-480, it is a snap to handle this:
- Direct To the first waypoint
- All the airways from that waypoint are LISTED by the GNS-480 - =

just push a soft-key for the one you want.
- Then you choose from a list of waypoints ON THAT AIRWAY where you =

want to get off. It is EASY!
Yes, you must invest some time learning the 480, but that's true with =

GPS. I found it mostly intuitive, with only a few things that made me =

think twice - like why it SUSPENDS at the MAP. I guess that puzzeled=20
Garmin too, because in V 2.0 it no longer does that.

One more really neat featu it sizes holding patterns based on your
ground speed so you'll do 1 minute legs if you just follow the line!
