No loss of signal... but I just sent my 396 in for service.

Long story short -it would just stop working for no apparent reason.
Screen would go black. Only way to restart was with a battery re-insert.

The only apparent pattern it that it would never happen in the a/c.
Only on the ground. Swapped everything except for the stick attenna
which I used 100% on the ground and 0% in air.

So back it goes for repair.

Has anyone experienced significant "loss of signal" hiccups with their
new 396?? Since getting ours a few months ago, we have had
several...some lasting 15-20 minutes. System shutdowns/start ups may
or may not re-initialize it. THe antenna is unobstructed and in plain
view of the sky. An older Garmin is still in our plane and works fine
so its not some GPS system glitch.

I've thought about re-installing the software. There is a new upgrade
on the Garmin site so it wouldn't hurt, but none of the fixes address
any "loss of signal" problems.

Any similar experiences out there???

Thanks!!!
