Cr-210 in another car
 

I'm thinking of putting a late model radio in my 914 just for the sake of having something in the car to listen to from time to time............and keeping it "Porsche". Is it possible to connect up just the basic power and speakers? Or does it require something special from the car after the unlock code is entered?

On the CDR 220, there was an input for the speed sensor. This allowed the unit to adjust the volume based on the speed. I don't know whether the 210 had the same feature or whether it will affect the operation if it is not connected. There may also be connections that affect the illumination of the controls on the unit.

Overall, I'd say this is worth a shot. You may want to consider bench testing it before installation using either a computer power supply or a 12-volt battery for your power source. Here's a video that shows you how: https://www.youtube.com/watch?v=QntZ3A4bG4w You should be able to find a used power supply on Craigslist.

Good luck.
