Hello everyone...
I hope I'm posting in the right section...
Can someone tell me what conditions must be met for the Concert II to accept (and play) audio signals at the navigation system's audio input?
The background is as follows:
The speakers on my mobile navigation device are, firstly, undersized, and secondly, they sound bad.
Turn it on.
Hardly thought of, already done

.
Let's connect it to the radio. What's the navigation input for, anyway?
I got the audio cables, connectors, and crimp connectors from the electronics store, and now I'm ready to get started.
Klinke an Navi, Stecker an Radio... Silent

Logisch, Codierung falsch... umcodiert... Silent.
Assumption 1.
Output signal too weak?
Assumption 2 (the more likely one).
'Pass-through parameters (signal from navigation to radio -> Hello? I want to talk!) are missing.'
So... now it's your

.
Thank you... Steve.
