Older 1999-2007 model year Ford vehicles don’t come with an aux input audio option and they have a cd changer under the seat instead. I made an Arduino shield that emulates the CD changer and injects my iPhone’s audio pretending to be a CD. The shield also handles intercepting the car headunit’s playback commands when you press the physical radio buttons on your car so it does a second emulation of a earphone clicker and passes headunit playback commands back to control the phone over the aux cable.

In short I can control my phone’s audio playback using my retro radio headunit using only a wired connection and no Bluetooth.

One of the easiest ways to add an aux audio input to a car is to get a radio antenna bypass box, like the iSimple IS31.

2007?! They were putting CD players in cars in 2007?! Are you in the US?

    Ford's first iteration of their Sync infotainment system came out in 2007. What were they supposed to use before that?

    I’m not sure if that’s surprisingly early or late

    I live in the US and had a 1991 Acura Legend with a six disc CD changer in the trunk (it was ahead of its time in a few ways) and have recently had a 2014 Honda Accord with a single CD player in the center infotainment area

      I'm not sure what I was thinking, I must have been tired and maybe mixed up 2007 and 2017. 2007 absolutely would have been CD player central with a sprinkle of Aux/3.5mm connector every now and then.

    Yep, the 2007 Ford Escape hybrid I have is a US model. The next year in 2008 was when the new Escape model design had the Ford Sync audio system with aux input.

    I had a 2008 Lexus RX with a CD changer and a cassette player in the dash. Old people is their primary target audience.

    My 2010 Audi (bought used) has a 5 disc changer and an iPod connector. Very futuristic.
