Colyn, I have an A36 Bonanza
with a 530W and a 430W. This has happened once on the ground. When
I taxied the problem/message went away. Antennas are external.

Has
anyone else noticed any issues with their WAAS GPS installation?
I
just convereted a 530 and 430 to 530W and 430W. My GPS
antennas are on a tray just under the glass section in front of the vertical
stab on my IVP. Since I got Waas I get "No GPS navigation - user
other nav" message. It happens on the ground, it happens whether
near buildings or not, it happens to both navs but at different
times. It lasts from 30-45 seconds typically.
One
theory that has been put forth is that the WAAS units look further down the
horizon (or need to to get a big enough constellation) and that I may have some
blockage at those low angles. So far I haven't seen this happen in
the air.
I
also converted my cessna 530 to 530W. I haven't noticed any
issues. The antenna is OUTDOORS in that installation.
