Hi, just got my 2006 Mazda 3 Hatchback! The previous owner said (that her son said...) that it is possible to add an AUX port to the OEM stereo, mounting it inside the glove box. Is that really a possibility? Or should I just think about upgrading to a newer head unit with Bluetooth, AUX and USB ports, etc.? And is that a major undertaking that needs a car stereo expert (8-10 out of 10 difficulty) or more like a 3-5 kind of DIY project?

Thanks!

not worth the time with the stock headunit.
get a Metra single din with lcd display mount
Pioneer DEH-X6900BT - Bluetooth handsfree and advanced features the stock unit doesn't have

IF you have a wire harness between the head unit and a CD player or tape deck, you can patch into that. I haven't had much success soldering connections inside car radios. Either way you need to add a switch or a way to fool it into thinking the AUX is actually the tape or CD.

It's really easier and better to replace the head unit with a bluetooth unit. Even cheap ones have hands free phone and the fancy ones have back up cameras and Carplay and stuff.

Thanks, that's what I thought. Is a replacement a DIY kind of thing or difficult to avoid breaking stuff and needs an expert hand?

Depending on the exact radio, there's two ways to do it. On my original radio from 2004, I had to go with an Sylfex Auxmod. It plugs into the bottom of the radio, not the back. A bit pricey, but it works perfectly.

On a later radio, you can sometimes get away with the that just plugs into the back of the radio.

I would post links to what I'm talking about, but I'm new on this board, so it won't let me. Just google for "Sylfex Auxmod" or "Mazda Aux Harness"

Oh man. Those things are junk. You're going to hate it, I promise.

On my 04's radio, I installed the Auxmod, then drilled a small hole in the front of the radio for the jack. Here's a picture of what I did, excuse the filth. :(

Thanks for the reply. All you need is a sticker that says "AUX" and it looks like it's OEM!

Yeah, well, I'll find out on Monday (delivery day) or Tuesday if the FM transmitter Bluetooth thing works well.

I like what you did but if I'm disassembling stuff for access, I think I'll just go the full stereo replacement route with Bluetooth, AUX, USB and maybe even backup camera and screen.

I have an '06 as well, and if your radio has a "Media" button then you can just plug a Goliton cable in the back and you get an aux cable. I am running ours into an MPOW bluetooth adapter so I can stream Pandora and receive calls.

The older units I think have an MD/Tape button instead and those use a different interface, but for an '06 with a Media button a $10 Goliton cable should be all you need.

Here is a link to the cable: https://www.amazon.com/Goliton-3-5mm-Connect-iPhone-Player/dp/B006FFCONA

If it is your first time removing the stereo (to get around back) it will probably take about 15 minutes taking care not to break things or lose screws. I can get to mine in about 3 minutes now but I have had it out a few times.

Thanks for the reply. I just went outside and checked and mine has the MD/Tape button. I did buy one of the FM Bluetooth transmitters that plugs into a 12V AC jack and for now it's enough. I use it mostly for music, not phone calls. I like the OEM head unit (little things like the outside temperature on the display) and that I can use it with gloves on (it's cold where I am and while the car gets warm, the steering wheel can be cold for a long time) and that it's all very intuitive and easy to use (not like the frickin' Sony in my now-for-sale old car). If anything, at some point I may pop for a whole new stereo unit but probably not for a few months until the weather warms up. (ditto for installing the low-tone horn that I bought to add to the car).
