I assume that the stereo powers up, but no radio reception and speakers are not working? You need to connect the blue wire from the stereo to the blue wire on the radio aerial adapter (with the fakra connector) and the blue wire that is coming out directly from the harness connector that attaches to your car. I recommend using proper bullet connectors for this (Halfords sell these for peanuts).
It looks like you have the right adapter mate. Did you check the harness that came with the HU, as I know that there will be some alternative methods for wiring-up the power side of things. Check-out page 8 in your Pioneer installation manual and look at the yellow and red wires on the wiring adapter that came with your HU: http://www.pioneerelectronics.com/StaticFiles/Manuals/Car/SPH-DA120_InstallationManual070714.pdf
For the HU to work it needs power, but it also has to 'know' when your key is in the ignition, otherwise you won't be able to turn it off (I think). I'm just guessing at this point though.
Thread is getting fruitful but I'm getting nowhere....
So i bought the £75 mounting Kit from Dynamic Sounds, The double din cage doesn't really fit and bends out of shape, they send me an adapter that doesn't even apply to my car and the ones they have sent me don't work or I'm doing something wrong.
Would really appreciate any help as I've spent the whole day trying to get this to work with no luck.
If i upload pictures of all the adapters im trying to use can someone confirm if they are the correct ones?
i can't believe i missed all this!
firstly i know you think the halfords guy helped... but he really didn't! the reason you paid for the connects2 wiring was so that you shouldn't need to be running power cables and such!
ok so firstly from the pictures i see above it all looks correct, seems that you have the right kit. HOWEVER i don't see the box that is supplied with the connects2 wiring... its a slim black box with something like 10 female pins on one end and about 6 female pins on the other. (the second picture you have up there is one of the connectors that go into that box) connect that as without it you won't get anything working. If you don't have this box then call up dynamic sounds and tell them so.
the box on the right in this pic:
now with the blue wires you need to connect it in a very certain way... you first need to identify the cables... you want the pioneer stereo harness which fits into the back of the stereo, on that there is a blue (blue and white maybe) wire that hangs off... thats one of the blue wires you need.
then there is the blue wire that comes from the harness where the above box plugs in (this is the one with the connector in the first and second pic)
and finally you need the blue wire from the aerial adapter (as your car is a 2004 use the ISO connector not the fakra).
now connect these 3 together and your car will get power to the speakers.
the red connects to the red, the yellow to the yellow, the green goes to a grounding point, and the purple on the back of the stereo harness goes to the purple on the connects2 box harness (for reverse camera sensing) and once it is all connected properly your stereo should power up just fine and work.
If this still doesn't work after all that then bring it to me and i will have it working for you before you go home!
alright no problem, i should be able to guide you through it.
now that box you said was on the quad lock harness... take the box off and plug it into the harness in the car and test.
