About to over-improve our 205. Open to any tips before we jump in!

This has been an interesting discussion!  Thanks to all!  I found this FAA legal interpretation online that seems to indicate that the clock on the G3X DOES meet the requirements of 91.205(d)(6) as it "displays hours, minutes and seconds in a digital format" and is "permanently mounted."  But there may be some Garmin documentation stating it does not.  I think that would have be in the STC paperwork but this is not my area of expertise. 

Baring documentation from Garmin, I'm going with the G3X as satisfying the requirement.

From that, the question is what do they mean be a permanent clock display.

The AV-20 has a clock display, but it is not displayed at all times.

I wondered that also but the AV20S has specific approval to replace a clock https://uavionix.com/uavionix-av-20-s-approved-as-clock-replacement/

Many of the "permanent"  dedicated digital clocks will display time of day, date, or a timer, but only one at a time.

Thanks to everyone for their ideas!  It was very helpful!  Attached is our final -  no changes now render. 

 

The big changes are the Electroair starter / mag and moving the compass off the center post.

That looks very functional.   If it were me I'd put in a PMA450b for the audio panel, but other than that, that looks like a very nice panel.

Looks awesome!

Do you have a radio 2 with nav radio?  How is it controlled?  Only through the 750 or both the 750 and g3x?

We already own the GMA345 so...  We'll just use that!

Yes, we are using a remote com for #2 (losing the #2 nav).  Controlled through the 750 or G3X.

I’m sure you guys thought this through , but the unlikely event of losing the 750 leaves you without approach capability (well asr/par are possible if available).

We did.  I don't fly single engine airplanes in "low IFR" (I fly jets in that stuff everyday but not singles).  And with 1000 overcast, I could get the Mooney down with ForeFlight on an iPad in a pinch...

Yes, I’d agree with that. If you’ve thought out your failure modes and have a reasonable plan, I think you’re in good shape.  The panel looks awesome and has so much capability!  Probably more info than your jets!

No question! I fly Challenger 300/350/3500s at work and even though they are "modern" they are still dinosaurs compared to what the Mooney will have..

I also forgot to mention that the G3X has it's own VFR only GPS so at least some redundancy there too...

So here's how it turned out!  We are very pleased.  A few squawks to work out but nothing major...

Can you tell us more about the annunciator panel removal.    I take it you kept the gear down and gear unsafe annunciators and they are mechanically dimmable.  Lo fuel level is now on the G3X.  Hi / Lo volts are on the G3X but this is not quite the same as 'overvolage' trip by the alternator control unit?  Hi/Lo vacuum gone.  Starter power - who needs that, but what is the basis for removal?  Alternate Air?

Not my area of expertise but my understanding is that if it's not on the TCDS, it can be replaced with alternative indicators at the discretion of the avionics installer.  There have been several threads here about removing the annuciator panel.  We are not the first.  Getting rid of Mooney "unobtainmium" was a primary goal of this install.
