I have Resco Radio installed on my phone and I would like to listen to the music from my phone (Mogul 6800) to my headunit in my car Pioneer AVIC-N3 http://www.pioneerelectronics.com/pn...503034,00.html so I decided to go to Radio Shack and purchase this 1/8" to 3/32 adapter http://www.radioshack.com/product/in...tId=2062471&cp and of course using the 2.5mm headset adapter the phone came with. I have this and used it to plug the stereo cable into http://www.pioneerelectronics.com/pn...492523,00.html , initially for my ipod to watch videos on the navi screen but works just as well. MY PROBLEM I am running into is, is plays the music fine (I can hear it) but w/ the headunit volume turned ALL the way and the phone volume turned ALL the way up, it is not NEARLY as loud as I would like it to be. VERY low in volume. I don't know if there is a program I can download for a volume booster, or a registry tweak. Let me know opinions, etc. THNX
