How to reset your DICE iPod / iPhone Integration Kit
If your DICE iPod Integration Kit for BMW / Mini Cooper is not functioning properly, in most cases simply resetting the device will allow it to begin functioning normally again. Here's what to do:
Turn off your vehicle and remove key.
Locate either the DICE module (small black box around the size of a pack of playing cards) or the 3 pin connector located in your trunk. Disconnect the large, 10-pin connector from the DICE module OR the 3-pin connector in the trunk, and leave disconnected for 30 minutes.
If attached, disconnect your iPod / iPhone from the dock connector or 2point5 spec.dock (if installed).
Reconnect 10-pin or 3-pin connector after waiting 30 minutes.
Turn on vehicle and select the DICE iPod integration kit by selecting CD changer mode (press CD or MODE on your radio until CD 1-01 [Mini, 3 Series, Z3, and Z4 vehicles] or TR 01 and CD 1* [5 Series, 7 Series, X5] displays.
