Garmin 396 'installation' in the Maule
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. Otherwise, the yoke mount looks fine and the unit itself has me drooling. NC to FL next week! 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. -- Dan C-172RG at BFM ______________ \0/ o/ \o |

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.

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

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.

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. JKG |

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. JKG |

Let us know if you come up with an elegant solution. Dave 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? -- "You can support the troops but not the president" --Representative Tom Delay (R-TX), during the Kosovo war. |

I may try my GXM-30 there just to see what happens. 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.

Garmin needs to provide a way for us to get rid of it without voiding the warranty. 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... |
