Hi all. First time on the forum. I purchased a plane with the Dynon systems installed. Love both. But had to upgrade the GPS antennae a few months back. Hadn't flown in in very cold temps yet. Yesterday flew and climbed up over the local weather for a XC flight. When OAT it 3 degrees F, GPS source lost and map screen went black with a red x. Flew over the weather for a bit and descended into warmer temps. GPS came back online when temps hit around 35F. Tested it again near my destination airport and same result. On the ground I opened up access and fiddled with all the wires/connectors. No problem there. Stuck a piece of dry ice on the antennae for a few minutes and sure enough, GPS source gone again and black screen. I've reached out to Dynon and waiting to hear back. Anyone ever experience anything like this? Or any ideas what under the plastic in that puck that would cause the GPS source to fail?
the following pics show the wires to the antennae, with no tension on them. A pic of the screen in flight as it's blacked out. My dry ice on the antennae, the screen on the ground after a few min with the dry ice applied. Warming the antennae with my hand, and the screen through the canopy after it's been warmed up. In the first image, you can see there is no gps signal ( inside the hangar) but the source is still there when the antennae is warm. When it froze, the GPS source entirely disappeared.
