Hello.... Call me a pessimist, but i gave up on both the Dice & IceLink, they both were giving me a lot of problems and the vendors did not help, i have a 2003 4.4i X5, with Bluetooth and navigation, but no DSP.... Example of the problems i had:-
-Music / ipod gets stuck
-Ipod continues playing when using the bluetooth phone connection

-ID tags disappear after using the bluetooth connection with my mobile
-Playlists do not play in order and sometimes music played in alphabetical order instead of playlist order
-Occasional distortion, requiring restart of the ipod and the car's system (i.e. remove ipod, start up the car & stereo, stop the car, reinstall the ipod, bla bla bla...)
-ID tags do not appear or very slow to show
-You have to restart the ipod a million times (i tried all ipod versions/generations, the most suitable are the old ones)
My advise is to stick to the original CD changer installed (if available) or just get the OEM Aux-in retrofit kit (Much cheaper and more reliable)... By the way, some X5's have them already installed....

PS, i tried all software up-dates available for both.... And none worked properly.....
