It is polarized incorrectly which means if you mount it in horizontal orientation you see practically nothing on the display. Yes, but it works just fine with my polarized glasses in the vertical mode. So I made a bracket to hold it at the edge of the glareshield to the left of center. Since the device and display are rotatable in increments of 90 degrees, and since all LCD displays I've seen are polarized in one plane or another, Butterfly had to pick one knowing full well that it would please some and offend others of the polarized sun glassed crowd. No way for them to win! bumper The latest Firmware Version of the Butterfly display is out 3.01 It has: New Features: • Nondirectional traffic is shown permanently (PCAS) • Supports PowerFLARM® CORE • NEAREST-Mode, always automatically shows nearest target • Units con"gurable • Enhanced Menu Improvements: • Better stability with many received targets • new dynamical menu for future extensions. • 3.0.1: Better font readability I just saw an ADS B target the fonts are much larger and readable. You need a special cable to update the firmware. Make the cable instructions and get firmware at http://www.butterfly-avionics.com/in...upport-english or send to your dealer or Craggy Aero. Richard www.craggyaero.com All, I looked at the update information, and although it specified what connector pins on the display connector (RJ-12) were to be connected to what pins on a PC serial connector, it didn't specify the connector itself or address the issue of how one determines whether or not the PC can supply 3.3vdc on pin 5. I emailed the Butterfly folks, and I have copied the reply here. You will note that the reply still doesn't directly address the 3.3vdc issue, but at this point I'm confident enough that its not going to be a problem that I plan to fabricate a RJ12-DB9 cable and give it a whirl.

That 3.3 V is the supply voltage. There is not likely to be a regulator in the display module. Odds are pretty good that putting 5 V on the 3.3 V supply input will kill it. Putting 12 V on the 3.3 V input will almost certainly kill it.
