the cable passes through metal panels.
The recommended mounting surface for the control unit is on the center console.

NOTE: Connector-protective covers are provided with the radio. They should be used for added
environmental robustness.
A mounting clip, which allows the control head to be mounted, is supplied together with the control
head. The installation must not interfere with the operation of the vehicle or its accessories, nor
disturb the passenger seating. The control head must be within convenient reach and viewing of the
user.
