try this

gauge00=gps!gps,0,0,150,250 (heres the base) change gaugexx as according to your gauges in your Vcockpit section

this is from the FS2002 default 737

gauge23=737-400!Start Valve Right, 1, 494, 35, 16
gauge24=Magnetic_Compass!Magnetic-Compass, 1, 294, 39, 39
gauge25=gps!gps,0,0,150,250

so I would change it to gauge25 and then change the positioning as nessacary so it would look like its suppose to in the VC once in that view

if you try that and it doesnt work let me know and Ill leave the other tip (I think this one should work) Ive never tried it before so as always backup your origonal (good luck)
