This may be a really silly question but I have just agreed to have a G500TXi installed and I have an STEC 60-2 autopilot. How do you tell the G500 to use GPSS instead of heading mode?

Yes, but I was unclear about how. For example, if you have a JPI EDM 930 installed then there is no point in replicating the display on an iPad. But maybe JPI makes a unit without a display that could then be used to drive an iPad which might make some sense. But if you have to have the JPI display on the panel it seems pointless to replicate it.

I don't know but the alternative would have to be a 225, a 650 and a 345 because I still need a transponder, so you save a 375($7995) and a 225($4495) but you add a 650($10,095) and a 345($4995) but the number of units to install stays the same so I can't imagine installation cost changes much.

I've read through all 10 pages of this thread but still have some questions. I am looking at purchasing an older M20F with a panel handed down from Noah when done with his Ark. So I have concluded that pretty much it all has to go. A couple of obvious points - money is not unlimited. If money were no object I'd buy a newer airplane, and equip it with G500 Txi and dual GTN750s and a GFC500 autopilot and ADSB In/Out transponder. So I am looking at a far more cost effective plan to get utility without necessarily being the coolest. It seems to me that dual GNC225s and a GNX375 would take care of all the navigation and communication needs. My thinking here it that is that you get the very latest in GPS guidance, but should the GPS fail or weather be so bad that an ILS must be attempted, as opposed to an LPV, the GNC225 is there for that. Apart from the lack of NavCom the GNX375 is the same as a GTN750 but with a smaller screen. Which brings me to my first question. I've read the G3X manual but the flight planning section is not definitive. The G3X can contain its own flight plans for VFR use and they can be edited on the G3X. It can also use external flight plans from a GNX375. Where the manual is silent is can the flight plan in the GNX375 be edited from the G3X? If it can, which given Connext seems plausible, then the smallness of the GNX375 screen doesn't really matter. Even if it can't I assume it could be edited from an iPad running ForeFlight or Garmin Pilot. The major advantage, as I see it of the G3X over dual G5s is having a nice MFD display. but there is an app from Guardian Avionics that suggests that you can use an iPad as an MFD and even as an EIS. The Guardian Avionics website is not clear, at least to me, how all this works. But if an iPad were mounted in the panel running the SmartMFD software would it be possible to remove the original engine instruments, as it is with a JPI EDM930? It seems that dual G5s, and iPad as MFD/EIS, 2 GNC225s and a GNX375, and a GFC500 would make a very capable airplane at less dollars. Comments?

Thanks for all the input. Maybe I will become one of you soon

I live in Fort Worth and am contemplating buying a Mooney. I have owned airplanes before, but never a Mooney and not in this area. I am looking for advice on a good A&P who good do a pre-buy on an airplane. Any helpful advice welcomed
