carkit: mute

[Anonymous]

Hi all,

Has anyone figured out how to mute a radio? What signal from the XDA could be used / could be used as a signal for some circuitry (I can design that myself).

Hey Robert.

I´m sorry to tell you that i could not help you, but if you get some hints or tips tey are welcome to me too....
I´m looking forward to create my own Car KIt, but the Problem is still the Mute function :cry:

Regards

Stefan,

Below two links to pages both claiming that (at least on nokia stuff) they ground the mute pin on the radio. If that is the case than the circuitry is not much of a problem.

Step 1: I will test if grounding really does it. I have 2 or 3 old radio's lying around, just need a volunteer to find them :wink:

Step 2: figure out how to detect that muting should take place. I need some help here because I am not to familiar with the XDA yet.

Step 3: build some circuitry.

Step 4: post it here (for review as well)
