GTN 750 parts

Today while turning the inner concentric knob on my GTN, it literally disintegrated in my fingers. I can still turn the inner knob by using the metal stub that juts out, but I really need to get a new one. Any idea where I can get just the rubberized inner knob for less than, say, $2,000?

That is a bummer, how old is it?
What about calling the shop that installed for you and ask them if they can get one or may have one from a parts GPS?

Visit your avionics shop like Gary Ward suggested.

Is it the same knob as this one?

The unit was one of the very first installs of the GTN from 2011 and the shop is no longer around.

I don't know what a 3D printer is, let alone own one.

I think you want to put "Garmin 430-00030-10" into Google.

Is that a direct replacement? I'd hate to spend all that dough only to find out it didn't fit.

I believe the G1000 concentric knobs are the same as the GTN. But "all that dough" looks to be a ~$25 bet, and one that you could possibly recoup at least some of it.

Type “knob” into the Sarasota Avionics website and lots of options come up. None for the GTN, but I suspect a rep could tell you which one would fit.

If you contact Garmin directly, they may surprise you and send a new one free of charge.
Garmin is a good company, and they like satisfied customers.

You are exactly right, I ordered it and if doesn't fit, I blew $35 (with shipping).

The knobs fit perfectly, so it was $35 well spent.

Thanks for the heads up. The price, which includes 3 knobs, is about $240.
