UPDATE: I found a thread that mentioned removing the WT530 mod to fix my problem. That worked, just in case someone else comes across this...
I just installed the TDS GTN750 and brought up the Black Square King Air to try it out. I have found that I cannot click the IN and OUT buttons to zoom the map. Additionally, I cannot click the ENTER button on the Comms screen to enter a frequency, and I cannot click the "K" button when trying to enter a waypoint. There are several other buttons that simply do not work - something is wrong... The unit is unusable in this state. Hopefully there is a solution. Thanks.
