GNC355 and G5s
I am looking at installing a GNC355 to replace one of my RT385A nav/coms. I also want to install a G5 to compliment the 355. I have been told to first do the HSI version. Others say replace AI first and then HSI later? I also have a TruTrak autopilot. My question is can either of these setups be tied to the TruTrak? With finances tight which would be the best use of funds? My old DG is not processing well so it may need attention sooner than later making decision easy. I would like to install another G5 to replace AI but funds may run out. 2nd G5 may be a later install. Another option that has been mentioned is use an UAvionics AV-30-C for the AI since the HSI would give me guidance from the GNC355. Any comments are greatly appreciated.
