i used to have a 2000 s500 and in that car the cup holders were where the phone should be is now on my 2006 s350. in this spot all i have is nothing a little cutout for a phone but my car is not prewired for the phone nor am i going to put one in. what i am asking, is it possable to retrofit cup hold into that spot like the ones that were there in the 2000 model s class.
