Q
Is this compatible with a Pioneer DMH-1500NEX?

Greetings Caleb. Thank you for your question. This is more vehicle specific than it is stereo specific. But yes that Pioneer is steering wheel control compatible, and this wire adapter would keep the vehicles radio controls on the steering wheel working on the Pioneer DMH-1500NEX.

Q
I heard that the unit only has an orange wire for illumination and not an orange/white wire to connect to the dimmer wire on pioneer and other units. Is that right? Seems like a big oversight!

Unfortunately you are correct, when I installed mine I was not able to get the unit to dim with the rest of the lights, I have to manually turn the brightness down, yes it's annoying but it only takes 3-5 seconds to turn it down if it is too bright for you.

Q
Will this adapter allow me to use the console "joystick" controls in my 2014 Mazda 6 in addition to steering wheel controls?

You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with your factory system. They will be able to pull up your vehicle and see if this will integrate. If it does not, then they will also be able to discuss other options with you.

Q
Siri keeps auto-activating, I've determined it is neither the aftermarket deck nor my iPhone. Did anyone else have this problem? The SWC did work, but only Vol +/-, Track +/-, and mode. Phone pick up or end call buttons do not work. Is this how it's supposed to be? Is it maybe the splicing?

Q
Can anybody tell me where the light blue wire goes? It's coming from the 12 pin connector that plugs into the little black SWC module/box. I'm installing this in a 2015 Mazda 6, using a pioneer 4200 NEX. Thanks for any help!!
