Wire Your Car Stereo for Bluetooth Music Streaming

If the easy and wireless Bluetooth streaming in modern car stereos has you green–blue?–with envy, this DIY project will help get you started on the path of Bluetooth input hacking.

Roofus, a Hack A Day reader and tinker, pulled out the stereo deck from his late model Ford car. What he found certainly wasn’t plug and play, but with some careful probing and tweaking he was able to cannibalize parts from around his house to enable Bluetooth-stereo streaming. Now all he has to do to send music from his smart phone is start the music playing and flip a switch on his stereo console to turn on the Bluetooth device embedded in the dash.

If it can be modded, optimized, repurposed, or torn apart for fun he's interested (and probably already at the workbench taking it apart). You can follow him on if you'd like.

    or if they happen to have an AUX cable input then you can just buy a $3-5 cable and connect your phone/mp3 player via headphone jack and play the music that way. that’s why i do

    @trinity343 The entire point was to eliminate clutter and wires.

    For those of us not electronically inclined, they do have plug and play units for this sort of thing. I have one from a company called Grom Audio and it works great. I stream my MP3s over bluetooth from my Android phone. I can also stream Pandora, Slacker, etc as well.

    There are also FM transmitter devices that are rather inexpensive from big box stores that do the same thing with no modifications to anything needed. They play through an FM station on the low end of the FM band. Bluetooth may be more “techie”, but does nothing that FM doesn’t do with respect to playing music from your portable computer device to your car stereo.

    I go the AUX cord route in my Jeep. My Patriot actually has a little flip up holder for my phone in the center console.

    This is more of “lets see if I can get it to work this way” project. It’s Blackberry Gateway BT unit that plugs into AUX in. Power comes from USB. I’d sooner get a $30 stereo with AUX in and the gateway to install it externally than to go through the hassle of of opening car stereo and trying to figure out what to connect the gateway audio and power to. Better yet. Car stereos with BT for streaming and calls are as cheap as $80-$90 now. It’s just a matter of making sure if it fits the car with or without the cage and harness.

    The only reason why I would ever consider doing something like this is if my car stereo was integrated with, say, AC and other functions of the car and getting one upgraded with BT was prohibitively expensive.
