i'm looking for input as to the best replacement radio stack for a C182. right now i'm leaning towards the Garmin radios. from what i've heard they're really the best. here's what i need, and what i'm looking at:
x2 com radios, x2 nav radios, in panel gps (Garmin GNS 530)
mode S transponder (Garmin GTX 330D)
audio panel (Garmin GMA 340)
i was also looking at the ICOM radios, but i guess it would be wiser to keep all the same manufacturer. it would definately be more aesthetically pleasing. does anyone know if Garmin even makes TCAS? should i be considering this as well?
