GPS 430 or 480?

That's interesting. What part of the country do you live in (assuming US), what
altitudes, what kind of equipment?

I still think Garmin's unlikely to upgrade the 430 to TSO-C146a capability.
It doesn't sound like good business sense, when they now have the 480.

Well, Garmin has said they would do so. There is an old press release on their
web site that says they'll have it by 4Q2004 for $1500, but they've backed away
from that date, even though last time I checked the press release was still
hanging out there. I called and asked about it a few weeks ago and they indeed
say they intend to have it by next summer. There was a thread here about it
earlier where I reported on my phone call.

TBH, they didn't say "TSO-C146a" but I inferred that from the capabilities they
mentioned.
