This occured in two different aircraft (a Comanche, and an Arrow) one
of them even had a GNS 430 w/ a GTX 327, so I'm not thinking that it's
some kind of interferance issue.

Of course, I am using the external antenna, have upgraded to firmware
3.40, and have even done the almanac reset that was suggested by
support. No dice.

Anyone else with similar woes?


Com radios can interfere with GPS signals, but I believe that Mike Spera
was suffering the same issues and performed some extensive
troubleshooting in his airplane. Eventually, I believe that he either
sent it back to Garmin, or had the Garmin dealer from whom he purchased
the unit do a swap.

I've found Garmin's support to be excellent, so you might want to give
them a call, explain your situation, and see what they're willing to do
for you.
