WX-500 displayed on the Avidyne is an option on all Cirrus models:

And standard on none, with any package.

SRV, SR20 & 22. I flew a Skywatch equipped SR22 a few months ago,
what a treat. Really helps with traffic awareness. I'm sure the
WX-500 is equally cool.

It's not a matter of cool, it's a matter of being able to fly when
there are T-storms around. Having flown with both Skywatch and
Stormscope, I have to say that Stormscope is WAY more important.

TKS is also an option. Not sure if it is K-ice though.

It is not. Further, it has a very small fluid reservoir compared to
what's available on airplanes of similar performance.
