It happened to me with my 196.
Finally discovered the problem. The plane had been in the avionics shop
and while there they had dialed a new frequency into the VOR (don't
remember what it was now). After spending lots of time searching and
testing a friend told me to try switching off all of the avionics - and
the gps came back. Turn on the VOR - lose the GPS! After tuning the VOR
back to a local frequency the problem disappeared.

Worth a try before you start spending money!

A friend of mine has a 12v Garmin 430 that simply does not pick up the
satellites. It worked fine about 3 weeks ago (the last time he flew) but
now it fails to find any satellite signals. One avionics tech said that it
had "lost it's almanac" and to pull it out and let it sit for a couple hours
and it should pick up the satellites and work fine. No such luck. All
power and antenna connections are good and nothing has happened to the
airplane or the equipment since it flew last. Any ideas? Anybody ever hear
of such a thing?

Thanks,
