I noticed there's quite a bit of confusing information about installing an aftermarket head unit into a 2011 Mazda 2. I thought i'd just post a link to a guide and some of my own tips. I have an Australian Mazda 2 2011, so it may vary for you based on locality.
1. Follow this thread to take apart your dashboard to gain access to/remove the stock head unit. http://www.mazda2revolution.com/forum/showthread.php?t=374
2) If you wired everything up correctly, you should see your device boot.

- I did not need a antenna adaptor as mine had a single pole rounded long plug that went straight into my head unit.
- The poster does not go into detail about how he fitted the unit in the dash kit. The head unit I had was double DIN but wouldn't fit with the dash kit i purchased. I had to sand down the mounting brackets to about 0.25mm to get it to fit. I then carefully levered the unit into place and used some flat screws to attach it to the mounting bracket.
- For a automatic car you don't need to unscrew the shifter knob, the panel just comes off.
- the wiring harness i purchased was not a metra branded one, and the wires were not labeled. I found the diagram below to be extremely helpful and accurate. Ignore the wire colour in the table. Match pin to pin. from the stock harness to the adapter and then from the adapter to your head unit as per its instructions. The illumination wire did not work for me despite many attempts, you may have more success than I. Everything else works flawlessly.
- If you want to wire up the steering wheel controls, either use a SWCI and follows its instructions, or in my case, as i did not use one, simply connect pin 13 to ground(24). You should then be able to assign steering wheel functions to software functions once the head unit it running.
- There is another 16 pin white plug with the old HU that handles the AUX cable functions. I've left this unattached for now until i figure out how to integrate it into the head unit.
- If you accidentally short anything, two fuses have to be replaced as below. Don't make the mistake i did and create a short circuit, make sure all your connections are either capped off or covered in heat shrink/electrical tape.
- Make sure you transfer the small white clips on the back of the old dash piece, otherwise your unit won't clamp in. You'll also need the small metal brackets and screws that secure the hazard panel in place. Pay close attention to them when you take the dash apart, so you know how to put them back together.
2) If you wired everything up correctly, you should see your device boot.
- To get the key lights working go to settings> factory settings > other > key light. Password is usually 126. You can also change the boot logo in this menu.
- Some people have said that GPS doesn't work well when the antenna is inside the dash. I've had no problems.
- Some people say that you need to position the microphone near your mouth(somehow?), mine is placed on the back wall of one of the storage boxes right next to the steering wheel. I've had no problems and tested extensively.
- Download a good offline maps software.
- Set your radio station presents to avoid white noise on startup.
- Finally make sure your device powers off completely(not just sleep) after 30 seconds following complete turnoff of the car. When you turn the car back on after 30 seconds you should see the boot logo appear. If it doesn't you need to make sure your accessory wire is correctly connected, otherwise it will drain your battery.
