One of the things I miss in the Insight is a outside temperature reading, my wife's Acura TL has it on the dash, it's handy.

With the Insight being very temperature sensitive for maximum MPG's, it would help to know the temp as you were driving. I also worry about the radiator block and how it relates to the ambient temp.

After reading through a bunch of old messages at the Yahoo! Insight group, it appears a few people have added a rearview mirror with temp/compass features.

I'm considering a mirror made by Magna Donnelly, it has temp, compass, and a garage door opener.

Have any of the other Insight owners installed an aftermarket rearview mirror? Any problems? I understand the attachment button may need to changed, how was this done safely, without damaging the windshield?

Or is there a better option for a outside temperature reading? Dakota Digital?
