My question concerns the addition of the GPS device that was included with the default aircraft. I am using other aircraft now such as PSS products, and i would like to be able to use the gps off of these panels.Is there anyway to import or modify and of the aircraft or panel files to include the stock gps included in FS9?

Yes,Open the Learjet (or another default aircraft) panel.cfg file with wordpad or notepad and copy the section labeled:(Window02)
