Klaus,

We think alike. I asked the representative from the salvage yard to make sure that the 4 digit security code was obtained so I would be able to activate the radio once it was installed. He said he is able to obtain the 4 digit security code by contacting his local Volvo dealer. I also asked if the radio worked? His reply was, when the donor car comes in, the radio is checked to make sure it works. Of course, he said, radios are sometimes "problematic" so they are warrantied. I hope the radio I obtain works out. If it doesn't you may see a separate query posted by asking the members of this community for sources to obtain a replacement aftermarket radio that will neatly fit into the existing slot in the dashboard. My private Volvo garage recommended an on line radio supplier called "Crutchfield". I haven't don't any research on this vendor, and personally I hope that I don't have to, but as I mentioned before, the radios on my two 1996 850 are approaching the 25 year mark, and unlike a bottle of wine, they do not get better with age.

I'm sure a current 2021 radio will have features that didn't exist back in 1996, but I will miss that "stock look" of my old Volvo radio. I guess we have to manage our expectations sometimes.
