I just purchased a 2008 CLK converable, It does have the Premium package which supposidly means it is prewired for phone, but I almost fainted when I heard what the dealer wanted to charge to add blue tooth.
I see no cap or connector of any kind in the arm rest.
Have you or anyone had success upgrading to bluetooth with some 3rd party product?
