Just purchased an 05 E-55 9000mi and love it!! It has two options that I'd like to learn more about. One is a Telephone system with VCS, has some type of plug in the center armrest but no phone! What type do I need and what type of interface? The second is I'd like to add a satellite radio, how hard is that? any help anyone can give me would be great.....

 

you mean you have a cradle in the center armrest?
if so, then it must be for MB's Motorola V710 phones.
for sat. radio, you can hook it up thru AUX input.
