I'm scheduled for my ADS B install in early April. Since joining MS I now have caught the bug. I'm seriously considering a panel upgrade. I currently have an older Narco audio panel, Genave marker beacon, two King 155's, a Cessna ADF, King transponder and a boat anchor loran. Considering a Garmin GNS530W, keep the 155 that has GS, Stratus ADS B, and new combi audio panel with built in intercom and MB. Get rid of 155 no GS, ADF (shouldn't need with the 530), King transponder marker beacon, audio panel, and loran. I currently do not have an autopilot. Considering the TruTrack or Garmin maybe next year, once approved. So should I install the G5 HSI, or a GI106? Will the G5 work with the TruTrack? Do I need to include the GAD29B in the initial install or is it upgradable when I install the autopilot? What's the best choice for audio panel. I'm already putting more $$$ into this than the plane will ever be worth. Appreciate any help. Oh by the way, will probably do an I Fly GPS OR Foreflight for ADS B in.
