There's not a lot of real-world data on the costs. A couple of articles that
I've read estimated it north of $60K minimum. It could go way north of that
given the shape of your panel and any "might-as-well" upgrades that will
come up.

I ahve been reading about Garmin G600 "galss cockpit" for a while
butthe information has been VERY limited.
I am thinking about upgrading my M20S but have hd problems even
estimating potential costs.

Any pointers here ? Thanks a lot in advance
