Howdy VAF folks - I've been pulling my hair out over this XM problem and ran across this thread. After flying about an hour I noticed I had no local wind data from XM on my 496/30A, then noticed I had no wx data at all - same problem as everyone else, but it gets worse: I've got the audio from my 496 mixed in with my nav audio (for terrain/obst/tis warnings). All was quiet until I was on final and when my 500ft warning went off the XM stereo came on
loud (I normally have it muted). Scared the you-know-what out of me. I spent 15 minutes trying to mute the danged thing through the software but had no luck.
Apparently whatever happened to the wx has also caused the audio page to lose it's program information and options. I'll unplug the antenna for now, but what an annoyance.
Before finding this thread I tried the following with no success:
- did a master reset on the 496
- reloaded the latest firmware
- loaded an older firmware version and let the xm antenna downgrade to older firmware
- loaded the latest firmware again and let the antenna upgrade itself
As of 30 seconds ago the XM data is still dead as is the audio page, but I'm receiving the free "demo" audio channel
