this was the one i had in mind http://store.qkits.com/moreinfo.cfm/K8055
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!Originally Posted by turbocad6
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.Originally Posted by psyrex
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.Originally Posted by turbocad6
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.
