I have done this for myself, so there is a heavy dose of personal preference here, but if anyone is interested in this MFD mod PM me your email and I'll send instructions (batches as and when).

It incorporates the F1 GTN750, and tidies up some of the EICAS elements that bugged me.  The list I can remember:  Shortened text fields that were creeping out of the eicas.  Fixed the "DIFF PSI" chopped text.  The electrical gauge's source data slightly changed (still faked, but uses the load as the base for one of the figures now so semi useful).  Electrical gauge's letters on the indicators font changed and position moved on the arrow slightly to be somewhat readable.  Removed the letter from the volt meter and changed "CAS" to better match the documentation.

Hello Chobber,

Very nice work! I was hoping someone would do this to the Meridian, the last obstacle to prompt me to buy it. PM sent.

Thanks Chobber... great mod..

One question... I don't seem to be getting a glideslope on any approach. Is any experiencing this? I tried multiple at KTPA.... I know the airport so I know when I am on glideslope so I hit APPR and it did work....but no visual glidslope on the PFD....

You're welcome!  I tried a couple of ILS 1L approaches at KTPA, one in the vanilla and one with the GTN, is this not what you are seeing?   Are you using the navigraph extension package addon from Carenado?

Correct. I do not get the GS in the PFD next to the altitude tape when I load an appr in the GTN. For example - load the GPS LPV appr RWY 1R KTPA. FLy the approach. The localizer is displayed in the PFD but the GS never displays. In the above pic did you load the appr in the GTN?

I do not have the extension packs.

Got you, no this was an ILS using just the nav radio.   I don't have the extension pack either, and the stock G1000 isn't capable of doing these approaches.   I would be interested to hear if anyone with the extension has tried the mod and how that behaves with gps approaches both in the G1000 and GTN.

I'll start digging through XML :)

So....   I don't see any magenta elements in the vertical deviation indicator for vnav at all, no magenta glideslope elements.  All that is there is the green indicator for loc ils approaches.  Tempted to grab the expansion for a look and see if vnav displays work there, and how the LPV approaches are handled.

In my experience, the glideslope indication will not appear doing a GPS approach with LPV/VNAV. However, the autopilot will follow the vertical portion of the approach even if it's not indicated. I put a small pop up RDMI gauge in which will show the vertical guidance. Once the autopilot couples to it, I close the pop up.

Thanks for looking into this.... If I recall in past GTN retrofits by Bert, he did modify the PFD files to see the glidslope. I use his mod in the CJ and it is there on GPS approaches loaded in to the GTN. I will send him a PM to ask if there is something in particular... I am not the best in xml but perhaps Bert can shed some light......?

I've mailed you some test files if you could put it through it's paces and come back to me, I've not had time to test it very much at all!

Thanks for all your help FLIGHTO!    The GS will now display in magenta on a GPS approach.

Navigraph AIRAC's only contain LNAV approach data, so 100% sure it won't be there.  I passed on the Navigraph mod for this one... I have a few of the ProLine21 birds from Carenado and those aircraft don't even scale the CDI for RNAV approach sensitivity. 

I've done some work on the Carenado ProLine and I notice they have a variable that indicates whether the route segment you're flying is part of an approach.  I suppose the G1000 Navigraph pack for the Meridian would have the same and you could use it to scale the CDI for approaches, but you still won't get vertical guidance.

This mod has worked perfectly, but after updating P3D to V4.3 the GTN750 in my Meridian with the mod doesn't seem to work anymore, it only shows a black screen. The standard panel shows up in my other Meridians. Anyone else experiencing this?
