TAWS And GPWS failure

[jamesrowe2002]

Hello James,

We are sorry.

What do you mean by a "TOPCAT database file"? with the TDS GTNXi closed and MSFS, please delete the entire "Navigator_XI_1" folder, located here:
C:\ProgramData\Garmin\Trainers\

Then with MSFS closed, please start only the TDS GTNXi from the desktop shortcut and click on the GTN750Xi button, does this fix the problem?

Best regards.

Hello, 

Thank you.

I’ll try that later. 

I changed the settings from TAWS A to TAWS B and on startup I get only a TAWS pass and no GPWS. 

Thanks 

James
