First off, thanks for all of your help. Whether you knew it or not, I was plowing through all of the old messages here trying to figure out how to get all of this stuff installed in my 1998 E320. All I can say is SUCCESS! And here is the finished product:
You'll notice that everything aside from the Nokia phone is hidden behind the paneled box that used to be the Mercedes Analog Phone. I heard the caution on the value of saving the phone parts, and I've put them away, so the car can be dumbed down again in the future, when Analog Phones are valuable collectors items.
It took me most of three days to get everything done but now that I finally finished, I'm very pleased with the results. I'll add some more detail later, but I was too excited to wait to tell you all.
Thanks again! I wouldn't have figured it all out without you!
