Dan, if I recall correct your Streak is running XCSoar. As such it can not be used as a flarm display. As much as I like XCSoar, it's flarm support is close to useless. I opened many enhancement requests in attempt to bring the flarm support to SeeYou level but they are not getting any attention. So you will need the small butterfly display which you should be able to find a place to put instead of your Zaon As I did. You'll also get a more reliable and accurate Mode C alerts than the Zaon provides. Sell your Zaon to cover some of your cost.

It's definitely true that XCSoar is unsuitable for use as a primary FLARM display, but this is somewhat by design. XCSoar's 'FLARM radar' was intended to complement the 'LED clock' type original FLARM displays, and warnings are intentionally left to dedicated hardware.
