    Mute on GPS Direction?

    I'm in the early stages of planning a system.

    I want to keep the existing head unit - I spend 90% of the time listening to the radio and about 10% to CDs.

    My primary use for a car PC is for GPS navigation, but I'd also like to be able to connect my ipod and play tunes directly off the HD, and use phone integration. My intended choice of software in Roadrunner and iGuidance.

    I definately do not want to watch TV or DVDs, or sat radio.

    My intention is to connect the head unit output into the line-in of the sound card, and then the line out to an amp, and then back to the original speakers. This way I can keep the orginal head unit working.

    My question is what happens when the GPS software gives directions - I've seen that RR has the factilty to drop the volume, but will this do both the line in volume, and the winamp volume if I've got the ipod going.
    Also, is it possible to have RR auto mute the line-in if I've got win amp playing?

    Cheers - as you can see, I've got a lot to learn!

    If you ask me, you'd be better off getting an AUX-In adapter for your HU and plugging your CarPC into that. Then you can keep the volume control on your HU too.

    The reason I hadn't planned to do this is because I'll be mainly listening to the radio, so there will be no way for the Car PC to interupt the music with nav instructions or phone.

    Thanks for the iGMon tip

    I've been reading some more. I've now discovered the Phidget board and relay control.

    I can use a relay to switch the head unit to mute when playing from the iPod (I presume I can add a command to the switch to audio screen to also close the relay, and vv).

    Can iGMon also trigger the Phidget relay if it has something to say?

    Thanks

    I don't know what all is implemented on Phidgets other than reading sensors right now. I don't have a board to test/develop with, so you'd have to either add some code to RR or write a plugin.
