Dont know of any...yoiu maybe able to retrofit the Mindstar G1000 into the Flight 1 172R (which is a FS9 model ported to FSX). The only other 172 is the Carenado one but that has steam gauges.
Carenado are working on a G1000 equiped 182 and SR-22GTS so I would bet that they will eventually come out with G1000 equipped 172 if you are willing to wait.
