I upgraded to Butterfly display 3.2.1 last week, with current Core firmware 3.00 (according to the PowerFLARM US website). I have checked connections, re-downloaded the update, re-inserted it IAW the normal procedure, and I get the cycling problem reported above (3 flights, about 14 hours of flying).. 3 other FLARM equipped aircraft say they see me properly, and I intermittently see them (when it cycles through that screen). I have been in contact with my dealer, and Butterfly, and they are investigating. For those who wonder what the 'cycling' looks like, I posted a you tube video, which I sent the link for to the factory: http://www.youtube.com/watch?v=u37YjIT9P-A.

After 3 e-mails back and forth to support, they suggest swapping displays with a known good one (a good idea, I don't know why that didn't occur to me); I will do that this weekend. Joachim is being very helpful from the AIR Store at Butterfly Avionics GmbH & Garrecht Avionik GmbH...

The following paragraph should probably be in another thread, but...
I guess I shouldn't have been surprised when the update to the PowerFLARM firmware was not announced to the registered users, or that it is unclear whether the 3.31 PowerFLARM update is for all users, just those in Europe, or only those with the Transponder issue (i.e., are there bug fixes in the change from 3.00 to 3.31?). If there was an 'announcement' here, I missed it and apologize in advance. The Core/Brick is a generally good product sorely lacking in communication to the users (one man's opinion). One comment - the Brick is bigger in volume than the Portable, and it takes a lot of space, which is confusing since it has less in it (that is, no batteries). If it could be re-engineered to be smaller vertically (may require antennae and the other connectors to be on opposite ends), it would be a much easier to install in gliders with very limited space behind the panel.

The display update fixes the clock font problem (thank you Butterfly), and the new fonts are much more readable; the new range selections are also good. So, an 'attaboy' goes to Butterfly for the changes and the announcement on ras, and once the cycling problem is addressed, all will be good with the display. I'll post the results of the swap here when it's done.
