For terrain, I think you need the "W" upgrade. there's quite a bit of
discussion of this below, but the basic info is about 3 AMUs, change
software, change GPS antenna, change antenna cable, new 16mb data
card, new Jepp Jsum software for USB downloads, terrain download from
Garmin, new USB device from Garmin.

I believe that the CDI on the nav page is GPS only. You can use the
GPS/CDI switch to control the mechanical CDI.


Thanks, Paul. From additional things I've discovered from the avionics
shops I've contacted, you're correct that the WAAS upgrade includes the
terrain, BUT the terrain is available as a separate upgrade, for ~.5 AMU.
Makes sense NOT to do the terrain if you know you're going to get the WAAS,
but if WAAS doesn't interest you (or is further down the road), terrain is
still an option....

Yes, the CDI on the nav page appears to be GPS only, as is the bearing
pointer (the BP is what I'd wondered about). Too bad, it would be nice if
the system would provide radio navigation capability on the main screen as
well....
