The picture I posted was the Argus 5000. The 7000 I have in my 210 is monochrome. A friend had the 700CE in his Mooney and was very excited about how color decluttered the screen.
My 7000 was installed around 7 or 8 years ago and I don't really remember the cost of the RMI, but I will take a wild guess and say it was probably something like $1,500.
In case you haven't already seen this, here's the Argus website:
