  1. I have a 2005 mazda mazda 3 2.3l. I’ve lost the functionality of the radio from the radio controls. I can access the mode, presets and volume from the steering wheel. None of the buttons on the radio work. Any thoughts? thanks

  2. Nickoli, we are happy we could help you with your 2005 Mazda Mazda 3 stereo wiring diagram needs. As for an auxiliary input, you will need an automotive auxiliary input adapter. This adapter will allow you to input any mp3 player or portable music player into your factory radio. This is the easiest and most cost effective way to add an audio input into your factory stereo. Here is the adapter you will need:

    Aux Input Adapter for 2005 Mazda Mazda 3

    If you’ve never installed car audio before, we advise you to take your car to an experienced mobile audio installer. Hope this helps. Good luck with your 2005 Mazda Mazda 3 aux input adapter installation.

  3. You guys were a great help! Mazda’s have funky color codes for the stock stereo and this seems to be the only place with them correct. Thanks a ton! I installed my first sub/amp today and it turned out great. Any leads on a good 3.5mm Input adapter for a 2004 Mazda 3 stock radio?

  4. Hello, please can you help me with wiring diagram of car stereo. I have 2004 Mazda Mazda 3 1.6. Is it same like in this 2005 mazda? Thanks

  5. B, most late model vehicles do not have RCA outputs on the factory radio to feed an audio signal to your aftermarket amplifier. You would have to install a line out converter to supply an audio output. Here is the Line-Out Converter you need:

    Scosche 2-Channel Speaker to RCA Line Out Converter

    When splicing in the RCA Line Out Converter, tap your factory rear speaker wires to get a full range audio source. We suggest you invest in some solid wire taps that wont come loose. These wire tap connectors will allow you to tap into wires without cutting and installs in seconds by hand with no crimping or tools required. If you’ve never installed car audio before, we advise you to take your car to an experienced mobile audio installer. Hope this helps. Good luck with your 2005 Mazda 3 amplifier installation.

  6. I am wondering if my 2005 mazda 3 has rca jacks on the rear of the factory deck for an amplifier hook up or am I going to need to buy a wiring harness? I would like to know before pulling it all apart

  7. Steve, if all your fuses are not blown, it would be hard to say what it could be. There is a possibility that a key component itself got burnt out. Our advice is to take your car to your local Mazda dealer and have them run a full diagnostic on the electrical system to figure out what the problem is. Hope this helps. Good luck with troubleshooting your 2005 Mazda 3.
