Im Picking up a 2005 S500 and was wondering what phones can be used in it because i want to use the motorola razor or something along those lines please let me know thank you.

 

Mercedes of course will tell you to use their product, as other phones can cause electrical problems. I have a Nokia cell I carry around and never had a problem with my cars. But there is always a chance that a cell could screw up something. In today's cars you literally sit in a hugh Magnetic Field, and a cell phone that has a surge or a reception problem, might disturb the field around the car and as I said some system could act up.

 

You can talk with any phone, but only MB motorola phones will interface with the set up. there are 3 major itms PSE, Splitter, and some others. The phone itself is locked to a particular "carrier" and can not be changed. The dealer gets a "kickback" when it is activated. The razor is not supported , the v710 and v600 are, and they now offer something for Sprint.
