Sandel EHSI SN3308 with 2.3 software update. Working when removed. Only potential issue is that the heading knob can sometimes get a little lazy where you need to turn it a lot to get a little bit of movement. It didn't happen every time, but when it does you have to turn it a full rotation to move the heading bug 5 degrees. Something may be loose? Something may be dirty? Ended up being replaced as part of a larger panel upgrade.

14 day warranty if not as described.
