Well, it came yesterday. Great box. Looks like the challenge will be
'mounting' the GXM 30 XM antenna in the Maule.

The thing has a big non-removeable magnet so distance from the compass
is needed. It has an extension cord and mounting screws but needs good
sky exposure... any thoughts are welcome.

Otherwise, the yoke mount looks fine and the unit itself has me
drooling. NC to FL next week!

Yeah, this is a problem.

I put the XM antenna on the dash of the car for the drive home yesterday, and
it affected my aircraft compass from nearly two feet away. That's a hell of
a magnet; Garmin needs to provide a way for us to get rid of it without
voiding the warranty.

Nature put on a booming L-6 thunderstorm for my test drive yesterday, so the
396 got a nice workout on the way home. Wow. This thing is going to take a
lot of stress out of flying the Gulf Coast.

Try tucking it up between the headliner and the fabric top of the fuselage. I
had my MBR antenna under the floor boards and it worked well through the fabric.
IIRC, M. Powell has a gps antenna mounted over the headliner in this way. If it
works, you can clamp a mounting plate to the frame tubes up there.

Garmin should know better. What were they thinking?

Mine came Wednesday, been foolin' around with it in the car. I think I'm going
to like it a lot, but that antenna thing is a definite drawback: the fact that
you have 2 separate antennas with two wires to manage, and the magnet.

Let us know if you come up with an elegant solution.

If I read the manual I found on their web site correctly, it won't work without
the magnet. Dunno why an antenna would require a magnet, though.

Good luck. The GPS10 has similar herculean magnets, and they affected
my compass no matter where I put the GPS10 on the glare shield. I
finally had to (carefully) pry open the unit and remove them.

Some folks with GPS10 units tried to get Garmin to take the magnets out,
even for a fee, and Garmin refused to do it.

My understanding is that the 396 XM antenna is glued shut in a similar
manner to the GPS10, and if so, some patient and careful prying will
open it up--but it will void the warranty.

The magnets do not affect the operation of the XM or GPS receiver.
There are reports on some forums of folks prying the antenna open and
removing them without a problem, but it does void the warranty.

They must have just sent out a big shipment, mine came yesterday
(promised ship date of 8/31). I came home to find it then had to leave
immediately for a flight lesson. Since it was a "preparation for
checkride" instrument lesson, playing with the new toy on the flight was
out of the question. Bummer.

I'll be taking it up on Saturday though.

I wonder why the GXM-30 has to have view of the sky? The WxWorx antenna
that comes with the ControlVision solution works fine in the side pocket
of a Cherokee. I may try my GXM-30 there just to see what happens.

And at any rate are we losing a little bit of perspective, complaining
that our W-compass's already marginal accuracy is negatively affected by
our much-more-accurate GPS?

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.

Would sticking a steel (or better, soft iron) disk to the antenna help
by keeping the field lines contained? My physics is a bit rusty, but
ISTR it would help...

Didn't seem to help much for the GPS10.

George, it's always a pleasure getting some Maule-specific advice.
Thanks, several times.

That's the question, will it work thru the fabric?

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.

It seems to work just fine up there thru fabric and insulation -
perfect! I can get as far away from the compass as the cable allows.
Looks like the magnet naturally finds a crotch a in the tubing to
magnetize itself too.

Don't think so. The steel or iron would become also magnetic, so it might make
the problem worse.

Great! Just keep it away from the aileron cables.

It would be reduced if the iron formed a closed loop between the North

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.

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.

Well, it definitely can sit up there in the tubing crotch, well clear of
cables, etc. But it definitely won't be removeable.

I'm now looking at just laying it on the floor in the baggage area and
stringing the cable along the floor. The extension plug will end up
right under my seat. The question I haven't answered yet is whether it
will receive well from there but I think it might given the extensive
composite construction on the Maule (composite = tubing, sheet metal,
fabric, and glass :-) )

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.

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.

For what it's worth, after charging overnight my unit's battery life
indicates 3:45 at full brightness (about 4:30 at moderate brightness)
with the XM antenna installed. It shows anywhere from 10-12 hours
without the antenna -- again, depending on brightness.

At this time, I have no reason to think these numbers don't represent
reality, but then again I haven't run it down yet.

I've had silly numbers (30+ hours) without the antenna, so perhaps it
varies from unit to unit. Still, it's not a big deal. I'm planning to
wire the unit into ship's power this weekend, so it'll be rather
academic after that. As long as it can last long enough to get me
somewhere safe if I lose electrical power, that's good enough.

You probably already did this, but upgrade the firmware to 2.40 and try
again. There's nothing specific in the release notes for 2.40
indicating a power management-related fix (and I didn't bother to read
back to the notes on the previous versions), but it shouldn't hurt to
upgrade.

If the problem persists the battery is likely at fault, as it contains
logic to transmit the state of the battery to the GPS firmware. The GPS
firmware, then, merely reports what it's being told. Try to borrow
someone else's battery and see if the problem goes away.

Good points, Doug. I'll try the firmware, and if that doesn't fix it,
no big deal. I notice, too, that the firmware notes mention an
improvement to Aviation In format. I'm hoping that fixes the CR vs.
CR-LF issue I've discovered that prevents use with King panel-mount
GPSs. That'll save me some work...

FWIW, I set up my 296 to keep the display backlight on for only about 30
seconds after it detects an input from me. This makes my battery last much
longer and the display is still reasonably legible with the backlight off.

Further testing shows the floor doesn't work. Back to the tubing crotch.

BTW, I tried and rejected the yoke mount. It places the display to
close to my eyes compared to the rest of the panel (aging eyes). I
fabricated a bracket to hang it from the panel over the flap handle.
May be OK but taking a trip this weekend to test.

This is my first 'portable'. I am not happy with the wires and location
options. Definitely a compromise over panel mounts, but I guess that's
no surprise.

Try putting it high behind the rear bulkhead. You'll be able to get it out
easily, but it might work better there. Michelle has her ELT back there. If it
works well, you could screw a metal plate onto the rear bulkhead (above the
removable part) and attach it to that with the magnet.

Trifocals.

I got my first pair eight years ago for precisely this reason. They're
perfect for flying. The bottom lens makes a yoke-mounted GPS clear, and
the middle lens is perfect for the panel (you can get the eye doc to
write the prescription for the distance you want).

Well, I ended up with it in the overhead crotch. I might stay with that
awhile until I figure out how much I'll want to remove it for land use.

Turns out that it can easily and securely be popped in and out right
thru one of the the headliner zippers and I just let the cable hang. OK
for now.

I'll have to write a trip report for the weekend. What a machine!!

You might consider buying another antenna for land use. IIRC, the price is about
$240.

There's a catch: The 396 XM antenna is also the XM receiver. XM will
only allow one receiver to be assigned to each subscription.

I guessed that was the case.

It's a shame that they couldn't get the GPS antenna in the same package
with the XM antenna/receiver. It seems to me that unless you mount it
on the yoke and keep it there (i.e. don't move it to your lap), you're
likely to lose GPS sats unless you're using the external GPS
antenna--which is another wire. Same story in the car.

One question: Do you guys protect the screen lens with anything, like a
PDA screen protector? Or is it pretty resistant to scratching?

I do on my 195.

The 195 was particularly bad because the screen lens was not recessed
like it is on just about every model after the 195, including the
296/396. However, it does seem that the screen would be easy to scratch
without too much difficulty.
