I bought a 2017 453 and the previous owner removed the Tac and whatever is behind and separate from it against the windshield.
Question: what the heck is that back piece that's about a foot long, flat and has an electrical connection??

Welcome!!! I'm sure we'll need a picture to confirm, but that sounds a lot like the windshield computer thing used for cars that were in Car2Go service. If so, there's nothing to replace. That device was removed when the car was taken out of rental service.

So I can get the tach replaced but I can take out the base for the computer........I'll try to get a picture on here.

I wonder if a renter stole the tachometer and Car2Go just never replaced it? But yeah, assuming no major damage was done you should be able to replace that.

As for the base for that computer, the last Car2Go car I've seen had the base held down by two regular screws.
