After finally giving up on using the FM Transmitter for my 2005 Outback, I picked up a Jazzy Aux-in Pro Kit. Let me say, I'm absolutely thrilled on the upgrade in sound quality with this kit. I'm very happy I got the GLI as well. Volume level is excellent! Directions are very well detailed and took me only an hour and a half to install. VERY happy with this upgrade to my Subie.
