I plan on adding a speaker there for nav.....

Thanks for the opinion! It means a lot from a forum veterano. Maybe I'll build the device and test it out for a week or so. I could also hook up a switch to the +12v power line of the LMT2 to switch the muting on and off whenever I would like. The parts are relatively cheap and it seems like a feasable solution. Thanks again!

I love it; just what I think I might need. I will run this through my AMP to get better sound from my PC. Excellent.

Thanks

I already have this in my SUV with the Alpine Nav and I like it. I guess you don't listen to your music as loud as I do. There's NO WAY to have my music going while the NAV is speaking. Now that will drive me crazy not to mention that I wouldn't even understand it.

Of course this is all personal preference too!! Good luck with your project and keep us posted. I'm interested to find out of your solution.

I hate to bring this up again but my car is being installed now and this issue just came up. Did anyone find a solution (new solution) to this problem? Or is the RCA source switcher the way to go?

Wow, I don't even remember typing what I wrote above.

Anyways, I'm working on audio integration with my stock system. What I plan to do is build a circuit not too different than one of the links above, which is to amplify and rectify a secondary audio source to get some voltage out of it. That voltage then changes the gain level of some rudimentary op amp setup so that source 1 is lowered or grounded completely, and source 2 becomes high. That way the nav, when speaking, will trigger the souce switch. A simple RC timer (or 555 timer, whatever) will then graduate the gain of source 1 back to normal, so it won't "pop" off and on.

I should clean up the schematic that I drew before posting it, but I'm in the middle of finals now (I shouldn't even be checking mp3car.com!), so I'll post it afterwards.
