Few pics of a recent Dynon install along with IFD540 in a PA28-140 (upgraded to 160HP)

We design the new instrument panels in-house and then we have a couple of independent local places we use to CNC the panels and powder coat them.
A certified HDX setup (including the STC costs, backup D10 AI, Arinc adaptor, AHRS, Magnetometer etc as well as an ADSB in receiver and an ADSB out remote transponder) is ballpark $17k plus 50-60 hours install roughly. The engine monitoring package for a 6cyl is about $1800 plus 25-30 hour install. For the models where we know where the autopilot servos will go (even if not currently STC'd) we can pre-wire the autopilot harnesses and have them laying in the place they'll be installed, the harnesses are $110 plus we generally say about 10 hours to pre-wire depending on the A/C model.
We normally sell an IFD540 for about $14k although if bought with the avidyne audio panel then we can usually improve on this a little. (IFD is 25 hour install unless we're replacing a GNS430 or 530 where the install time in much much less)
The other factor to consider is the cost of the new instrument panel itself. Most places we called up as secret shoppers were wanting around $6500-7500 for a new panel. We have been doing these more around $1500-2000 depending on A/C model and complexity plus a little more for powder coat etc but that figure includes the installation of the panel.

So basically for a full HDX/IFD540 setup you're looking $33,000-35000 in equipment and $12,000 low end labor. That quote actually blows a lot of places out of the water.

Interfacing the HDX with a TT autopilot is a grey area- speaking with Dynon it is not approved to be interfaced, neither is it on the TT end- so we assume that the shop that did that particular install/interface had it field approved. As far as I'm aware it follows the heading bug of the HDX and you set your ALT in the TT head but of course you'd flip the switch for the TT to be controlled by the IFD for LPV approaches etc anyway in that scenario. If the Dynon autopilot was in control then you could have the HDX controlling you all the way down. We're still waiting on the step down altitude labels being pushed from the IFD to the HDX (as well as to Aspens) but that will come, so when it does the IFD/HDX combo will be just as powerful as a GFC500/GTN750 setup.
