2007 Ford Focus Aux Audio

The 2007 Ford Focus SES I have has a CD player stereo with a giant AUX button. In the glovebox, there is a 1/8″ female jack for plugging in an ipod, iphone, or whatever. On that same jack/housing, there is a rocker switch to turn the power on to the jack itself. Try as I might, I simply couldn’t get anything from the stereo when I hit the AUX button. The display would always read “No AUX audio”. I was assured that thisĀ Ford Focus AUX audio was functional when I got the car…

After removing the front of the dash and the 4 screws that hold the head in, I found something I wasn’t expecting to see. Evidently, Ford installs a silver box called TripTunes in lieu of a dedicated line-in. This acts like a built-in FM transmitter and as you can see, has a switch to select the frequency you’d like to broadcast on. (mine was set to 88.3 FM).

So…if you have an AUX hookup in the glovebox and the AUX button does nothing, try plugging in your device and tuning to 88.3 OR 87.9 to see if you can get any love from it.
