This is a post on how to install the Sylfex aux audio input circuit card on a Mazda6 2006. I got the idea from the tutorial at mazda6tech.com; many thanks to them! Without their guide I wouldn’t have been able to do it. I decided to take my own pictures and create an updated guide for the 2006 Mazda. I ended up having to do the procedure twice, since the first time I forgot to reconnect the antenna cable to the stereo. At that point, I decided why not take pictures of the procedure, since I was now familiar with it.

The whole reasoning behind using the aux mod is savings. It cost only $60 for the card, which plugs into the stereo underneath, and you simply extend an audio cable from that card, and make a port somewhere on the front of the dash, to enable audio input from your MP3 CD player, IPOD, or whatever. An audio cable with headphone style jacks is about $10, and approximately $5 for a female headphone jack to mount somewhere on your dash. So total cost about $75. I completed the installation and was amazed at the sound quality, much better than an FM transmitter.

Consider using this over replacing the factory radio with say a cheap $100 car radio, a new console and a wiring harness. A new console from Crutchfield’s is $179, and a wiring harness about $13. So you’ll spend close to $300 if you choose that route. That was a big motivator for me to go the aux mod route. No problems since installation, and I’m happy with it, plus I saved money.
