9.When unsoldering or resoldering the coax cable, be very precise and use the exact correct amount of soldering, not too much, not too little. The RF level towards the car connector can be affected drastically by bad solderings.
8.When the spring is taken off, the RF/Logic unit can be lifted. The centre bolt (MMI support) can now also be taken away. Note that the centre bolt is not symmetric (comparing both ends). The shorter end fits into the MMI board.
10.The RF/Logic unit is 1 item, it should never be disassembled . Separate parts are not available. The IMEI number in the RF/Logic memory has to be equal to the IMEI number on the battery plate assy.
