The cost of a G500 retrofit & install is so high most of us with older airframes won't even contemplate it. But if the plane is one of the many already equipped with a GNS or GTN navigator, like your 182, the G5 and replacement autopilot starts to look interesting, especially for anyone regularly flying IFR.
On another forum I asked the Garmin rep (Steve) what the cost of a setup would be that he had posted a pic of. He gave me the price not including the GPS if you didn't have one. Here is the post and pic. His price does not include the GTN650 but does include the autopilot and both G5s. $12,119 retail without installation costs. Street price could be lower.
Yes, the GFC 500 autopilot system shown with GTN 650 is one example of a fully functioning system capable of performing just about any mission including legal single navigator IFR enroute and LPV/ILS instrument approaches.
The GFC 500 system is inherently capable of following all navigation guidance from the GTN including roll steering, so GPSS capability is included at no extra charge. When you see curved paths and holding patterns for instrument approaches shown on the GTN moving map, you can be assured that the autopilot will follow that path guidance.
The GFC 500 autopilot for C172 is expected to be $6,995 and the dual G5 setup with GMU11 and GAD29 is $5,124 if you don't already have 1 or more G5 units.
