Finally!!!!! After 3 long years with an 01 S500 Sport, I finally received my 2004 S55 AMG Benz! NASTY!!! This car is great. I had the Passport 8500 in my old S500(my first mercedes BTW), and like it, but am looking to upgrade to the PassPort SRX in this new Benz. Anyone have anyexperience with the unit, have it installed etc...? THanks for all your help.
