Garmin GPSmap 496 in Challenger

[soardtk]

Has anyone successfully used the Garmin GPSmap 496 w/ XM weather in a Challenger cockpit?

Thanks

Not in a Challenger, but having used it in another turbine a/c I can remind you that the XM weather stops at the border... Nothing outside the continental 48. There may be another subscription for wider coverage, but I don't recall there being one two years ago when I used the 496.

I've tried to use the GPS and XM recievers for our EFB's in our 600, but they can not see throught the electrically heated windsheild. I think that could be a problem for you too.

We've been able to get reception of both GPS and XM on 2 out of 5 flights. We are using it on a CRJ200 (Challenger 850). Garmin didn't have any info of it being used in Challenger's so I thought I would ask here.

Thanks

Our D.O.M. has said they only will transmit with acrylic windows. Heated glass windows block the transmission.

I use mine in an Astra with no problems. Heated glass.

My understanding id that the angle of the windshield had more to do with it than anything else. Ours worked fine in the 400A with heated glass, but there was plenty of room to move it to the front. I have also used it in an Excel with heated glass. I think the steep windshield causes the problem on the Challengers. Also, make sure the XM and GPS Antenna's are at least 6" apart and the wires are not strapped together.

Works great in Hawkers and Beech jets. We place ours along the side window that has the best Southern exposure.

works perfect in lears 20 and 30 series

The 496 works great with acrylic windows. We used it in the CJ1 and CE550 with no problems. Tried it in the CE750, couldn't even get a signal.

"Ram Mount" sells a glareshield bracket that works well with the 496. I miss using the 496.

If you put the antenna in the farthest forward corner on the center of the dash right next to the center support, it will work fine.

 

[soardtk]

Thanks for all the replies. ILOVEBEER, I'll try your suggestion also.

We use the 496 with XM in our older Citation II....GREAT piece of equipment for situational awareness. I wish we had the add-on that allows for a TCAD-type display but its not financially worth us since we're getting a new plane in less than a year.

Lear 45 and 40 worked at times, and only when going straight south...worked perfectly in a Citation Ultra, but in the lear its a waste of time , a combination of the glass windshield and the angle of the windshield seemed to kill it.

so it was sold on ebay...oh well

Same with us. We tried one out and had to run the antenna from one of the PAX windows. Could not get a signal through our heated windows. The rear cockpit windows are not heated, however there must be enough interference from the forward and eyebrows that there was just no signal.

We did install XM for the pax, and with that we get downlink WX on our MFD. It is GRRREAT. That would be the way to go for bigger planes imho.

Works fine in both of our company Challengers, 600, 601.

Where are you putting the antenna's? Are you using the suction cup mounts for the satellite antenna and just laying the XM antenna on the dash?

Thanks

 

[AV8TR70]

laying all on the dash with the 601, the crew on the 600 uses the window mounts, but either works fine.

I had issues in the hawker finally got it to work on the side window
Can you say Faraday cage?
Electromagnetic shielding is the process of limiting the flow of electromagnetic fields between two locations, by separating them with a barrier made of conductive material. Typically it is applied to enclosures, separating electrical devices from the 'outside world', and to cables, separating wires from the environment the cable runs through. Electromagnetic shielding used to block radio frequency electromagnetic radiation is also known as RF shielding.

just wanted to throw into the pot that we have used a 396 with xm antenna sittin on the dash of our g2 for 3 years with no probs.
