I'm attempting to tap into my front left and right speakers with an RCA converter to plug in my Mio GPS unit. I've found some wiring diagrams for wrxs up to 2005 but I don't know if its the same. This is what I've found so far:
Does anyone know if this is what I should go by? Also, once I hook up the sound for the GPS to the radio, is there going to be interference when the GPS tries to output sound when I'm playing music?
