Thanks Tim,
I don't have the XM WX (GDL-69) so I'll have to see if the GA37 is even an option for me. Since I upgraded to the GIA-63W (WAAS) and SVT I'm hoping that DAC will release SW that will allow the GTX345R to get its position input from the GIA-63W's. This could save me from buying & installing a 3rd WAAS antennae.
Thanks again,
Brian
