If your car has a factory fitted cradle in the centre armrest for either the Nokia 6150/6210/6310/6310i then you will require a ViseeO MBU-1000. The base of the cradle should be fixed in the car and will not be removable. The section of the cradle which holds the phone may be removable but will remain attached to the car via a "curly cord". This system is generally found in cars made between 1999-2004 but is not limited to this time period. This type of system is not found in USA spec cars.

The MBU-1000 will not work with any aftermarket fitted kit where the cradle may be mounted on a bracket next to the radio. The MBU-1000 will only work with Mercedes-Benz and no other vehicle makes.
