Matt,
Just a couple comments, I'm a 480 user. The two boxes work
differently, buttonology. So if you learned on a 430 and then got a 480 in
would seem backwards or just "weird". You'd have a bit of a learning curve
to climb with a 480.
The new 430W will be much more like the 480 in speed. The 480 updates
5 times a second, but the current 430 updates once a second, big deal on an
approach. One of the reasons the 430 WAAS upgrade has taken so long is the
FAA wouldn't give Garmin approval with at the slower speed. So the 430W
will have mostly new guts inside, instead of simple software upgrade.
Weather, especially at long ranges, would display very slowly on the
current 430. That might be one of the reasons they limited the XM
capabilities on the 430.
The new 430W will also have full XM display capability. But I agree
with Colyn, get a GMX200 (new replacement for the MX20). That unit with
weather, terrain, etc. can make any pilot look good. As far as the display
goes, the GMX200/MX20 leaves any of the GPSs in the dust. I would rather
have a 430/480 and a GMX200 than a 530 alone.
I have an MX20 and was considering getting the GDL69A for XM. But the
MX20 only zooms out to 250nm, not enough to see the "big picture". I
bought a 496. Other than the small screen, the 496 is a very powerful
little box. The new GMX200 zooms out to the whole country like the
396/496.
Bottom line, I would compare the new 430W to the 480 before making a
decision.
