Hi everyone,
I know it's been asked so many times, but I can't work out how to fix it...
I've bought a whole speaker upgrade system, and I can't use any of it without a new HU.
I have purchased the pioneer deh-x5600BT.
When I plugged it in using the included ISO, it does not power on at all
I have swapped the yellow and red wires around and it hasn't made any difference....
Does anyone know what I should do?
I understand it's something to do with ACC and I should get the feed from the 12V cigarette lighter, but is that the way to resolve it? I thought getting a feed from the 12V was to make it turn off automatically, not to give it power?
It's not powering up at all.
I tried another pioneer I have, with another ISO (which doesn't fit into the new HU), swapped the red and yellow around, and it worked....just not this new one...
Should I try and fine another ISO or what shall I do?
I look forward to hearing what all you experts have to say! You're all great

Thanks!!

The hu needs 2 power feeds
1 constant 12v+
1 switched 12v+ feed

Most cars now are can bus ie the cars brain says turn on not a power feed

So whats happening ia you are only giving 1 feed atm so stereo wont wake up

Ah okay.
So if I do get a feed from the 12V cigarette lighter, it should work?
Thanks again.

Here is a picture of the ISO which connects into the Pioneer HU I have.
Which plug should I put the switch feed wire (from 12v) into?

Hello again Ziggy, just wanted to tell you that I got the feed from the 12V and it's working perfectly! Thank you for your help!!!

Can I use the cables that come strict from car to make my new stereo work or do I need to have an adapter?
