My Ride: 2006 325ci vert
In 2002, BMW changed the antenna leads, so you will need an antenna adapter. You can get one online or go to the install bay at Best Buy. Do a search for "antenna adapter" to get the part numbers you need from Best Buy. Also, you will no longer need the diversity antenna, so just tuck that back into the dash opening. When I did my swap, I did not change any amplifiers and my new HU works fine. Regarding the DICE, it is my understanding that you must disconnect the CD changer, if you have one, in the trunk and connect the DICE unit, or if you don't have a changer, just connect the DICE to the CD changer connections.
