Aye.

About every 6 months I send Garmin a note. I keep see them developing STC's for aircraft types and fleets smaller and less expensive than ours - and I make sure I point this out. If people keep registering their interest for their new digital APs, we may get some action.

Yeah. I'm probably overdue to send them a nag myself.

An update, I had to replace my AI and DG instruments due to a 4-6 week back-order on the bearings, The shop offered new instruments, and yes compatible replacements for the 400 autopilot, for $300 over the overhaul! Still having servo problems, having gifted servos from a SOAPA member checked by Mayday Avionics. If these don't work I'll have to go with (hopefully) serviceable servos from Preferred Airparts at $1700 for both. Or the $2500-$2800 rebuild per servo? I thought I found a new autopilot, S-Tech 3100, but it's not authorized for the C337! I'll keep you updated, and thanks for your support.
Regards.

Thanks for the updates!
I haven’t dug into my autopilot yet as working on hydraulic issues
The s tec numbers are something of a stunner
But, I have kept my 182 and it has s tec system 50. Good wing leveler and will track course after lining things up. Not as capable as the 55 but point is s tec may have some less pricey alternatives....
But still “stout-ish” as will involve new install.

That is much the same from the two independent shops I've checked with.

Garmin, my avionics guy, asked his Garmin friend and was told the C337 wasn't going to happen, not enough airframes to justify the certification expense.
