I have a 02 ML320, I was looking at http://www.alldata.com/tsb/Mercedes-...-350/3501.html. I have my XM Radio directly FM Modulated, but is there a better solution to setting up the satellite. From what I thought the MCS was the same from 02+ ML's. Is it possible, and how because these instructions are very confusing. I have to turn off my XM Radio power for my regular radio, its kinda a hassel and im hoping I could get a better way to work with the MCS. By looking at this, it seems harder but convenient in the long run while operating.




Thanks in advance.. Benzlova
