ccrt 700. External source.

[Cumbria]

just been looking through the ccrt 700 manual and noticed an external source can be connected to the ccrt 700 (for example a navigation system) Does this work on the carin sat nav & if so how do i do it. Would this do away with the speaker in  the kick panel.

The Carin does not provide the necessary Mute line to do that.
