I originally planned for a 625/255 combo and based on some flawed logic decided to get the 650. I didn't understand how the G3X works with the 650 and figured I could look at a VOR or the GPS pretty interchangeably. But that isn't the case.
The HSI only looks at one thing at a time, so you can't really check on a VOR with the Nav radio while following a GPS track. You have to select at the 650 to change the output from GPS to NAV radio and back to check on a VOR. Same for an ILS or other NAV source.
Also I figured that a failure in one part of the 650 wouldn't affect the NAV much because it has a separate power supply and board. But if the display isn't working then both GPS and NAV go away. No redundancy in what I have right now.
So now I wish I had the 625/255 combo. Or I wish the 650 would put out both the GPS and the NAV data to the G3X. And that the G3X could show the NAV data separate from the GPS, with maybe a popup HSI and an OBS.
Can't figure out how to do a VOR check or get a fix with GPS on autopilot; don't think it can be done.
I know a lot of you don't care about VOR/ILS in the GPS world. But is there something I'm missing in the functionality that will give me more what I want?
