I'm sorry, but I just don't believe that the XM antenna works while
stowed in the side pocket. I have a difficult time getting a good
signal for weather even when it's on the glare shield, unless it's in
just the right spot.

Are you sure that you aren't getting the antenna and receiver confused?
With the Control Vision solution, they are separate, but the receiver
and antenna are integrated into one unit with the 396.

You may be right on my having the receiver and antenna confused,I'll
have to double check. I read it in an Aviation Consumer article, plus a
pilot I know who has one told me that, but they may have been referring
to the receiver now that I think about it.

Btw you were right, I checked with teh guy who had it and he said that
the receiver went in the side pocket and the antenna was a much smaller
piece that he had to put on the glareshield.

That's what I thought, as the little antenna seems to be sensitive to
position.

On the other hand, the Garmin GPS10 (Bluetooth GPS) that I use can get a
3D lock in the middle of the first floor of my 2-story house. It's
incredible. It doesn't surprise me to hear that the 396 has similar
capabilities.

Followup:

I got reception on the GXM-30 weather antenna with it sitting on my
dining room table, probably 15-20 feet from the nearest window. I
wasn't really expecting it to work; I was sitting there playing with it
and programming in my flight plan for the next day, and to my surprise
weather data started coming in.

In flight I haven't tried sticking the GXM30 into the side pocket of the
Warrior because when I put it on the glareshield (on the far left side,
where the glareshield slopes down sharply so there's probably actually a
good amount of stuff between it and the w-compass -- located there the
top of it was probably pointing out the left side more than up) I got
good reception and it didn't seem to have a noticeable effect on the
w-compass.

With the GPSMAP396 on the yoke mount of a Warrior, I got good GPS
reception without needing to use the external antenna. I hooked it up
and turned it on early in my preflight, by the time I started up it had
full reception and wx data downloaded.

Battery life seems excellent so far, I had it on for about three hours
without plugging it in, and the battery meter still showed at least 7/8
charge

I'm glad I waited to buy until this one came out, and glad I bought it.
Great box!

Ditto for my dining room table. :-) I was surprised that it also was able to get
a GPS position on the dining room table. My Garmin 196 was unable to get a
position with the two of them sitting side-by-side. The 396 seems to have more
sensitive GPS receivers.

Good news. Thanks for that report. I haven't been able to fly with mine yet.

More good news! My 196 wouldn't work on the yoke of the Mooney without the
external antenna. I'll try out the 396 as soon as I get the plane back from
Sparkchasers.

Now that's really good news. I was concerned about the number of wires. If the
GPS reception is good on the yoke, and the battery life is good enough to leave
it unplugged, then life will indeed be good.

I agree. Haven't flown with it yet, but it's great for watching Katrina on the
dining room table (that's the hurricane, wise guys).

You can't get live weather without the external GXM30 antenna, because
that is where the XM receiver resides.

Not so fast on this one. I turned on the GPS this morning for the first
time after that flight and the battery showed over 3/4 charge, so I
drove into work with it, about a 40 minute drive. Just as I was pulling
into my parking space it complained of low battery and immediately
turned itself off. I turned it back on and the battery meter showed
over 1/2 charge.

Conclusion: Don't trust the battery monitoring software, and don't
expect any real warning of an impending low-battery shutdown.

Btw adding the flight and the drive I figure I got a little over 3.5
hours out of a full battery charge, with the GXM-30 plugged in the whole
time. I guess I can't really complain given Garmin's promise of 4 hours
and Aviation Consumer's observation of 2 hours.

Conclusion: Don't trust the battery monitoring software,
and don't expect any real warning of an impending
low-battery shutdown.

Amen! Mine was showing 17 hours' life, so I didn't bother taking the
power cable into the plane, and 40 mins later, the thing died!

Don't you have to cycle Lion batteries a few times before they reach
maximum charge? For my laptop batteries, the manufacturer suggests
running them low and recharging once in a while to help ensure a more
accurate battery life indication, so there's some tie-in with the
software that guesstimates the battery life.
