To disarm the radio antenna, begin by unscrewing the left side rear seat assist grip and then proceed to unscrew the three clips on the rear left part of the headliner. Then, lower the rear part of the headliner slightly and fix it in the lowered position to provide the working space between the headliner and the roof. Following that, it is appropriate to unscrew the retaining nut and clips as well as the antenna, while during the installation, the procedure should be reversed. Regarding the Bluetooth antenna which is situated at the top part of the control unit, dismantle the unit, and then unplug the wires for the antenna alongside with disconnecting the screws that hold it. In the same way as with the removal process, the installation for the Bluetooth antenna also proceeds in the opposite sequence.
