My brother recently passed me his 2003 mazda 6. The cd changer no longer works, the radio drives me crazy they play the same 6 songs on a loop on all stations . So i am currently stuck using a useless fm transmitter, the thing is horrible I've been looking into the aux mods from the sylfex website but they're out of stuck till "mid march" but they still haven't responded to any of my e-mails. I was wondering if they are the only place i can get one of these aux mods for my 03 mazda 6?
