2002 V70 AUX Adapter Installation

pacuthbert

Hey folks,

So I've half way through trying to install my after market AUX adapter. I wanted to keep my stereo unit original with the whole hidden cup holder and all. The stereo unit that's on the Volvo is a HU613

So I'm almost done, but I'm stuck on one bit that I need to make it operate.

According the the manual, it's "plug and play" so I just pop on of the wires on to the CD Changer output at the back of my head unit. I've done that. Here's the bit I don't get. I've got a yellow wire that dangles out of the female CD changer bit, which says I need to connect it to "Power Source +" which also comes with a bridge clip.

For the life on me, I don't know which is the "Power Source +" I can't find anywhere the bridge clip clips to. The stereo unit has 3 holes!

Any pointers would be much appreciated. Would love to get it all hooked up tonight if possible, but that's a stretch I reckon.

I have tried googling, youtubing, all short of emailing the seller to ask for help. Thought you folks might respond a little faster. If you need photos, let me know.

Thank you so much!

Cheers,
Ashley

I tried to find the unit you're referring to on ebay. It sounds like this: http://www.ebay.com.au/itm/171989677991

Not sure on some of your terminology, so please read this CAREFULLY. Without any pictures, more info, etc. I don't want to be responsible for frying your device/stereo.

The auction text was in German, but he does list 11-14.6V. Digital stuff runs on 5V, not 12V. Since the device must be intended for a car, I assume the 'box' has internal circuitry that steps down and regulates the car voltage to a smooth 5VDC. You say there's a wire that reads "Power Source". Then I would ASSUME that is what that wire is for - simply 12V in.

So if I understand you correctly, you simply want to know where to get power from to power the device. And yu would probably want the device only powered on, when the stereo itself is also on.

I do NOT know if this is accurate for your car, but I found this:

http://www.tehnomagazin.com/Auto-radio-car-connector/VOLVO-Car-Radio-Wiring-Connector.htm

(Hit CTRL and F on your keyboard and type 613 and hit ENTER. There is a diagram there of the stereo pinouts.)

Is the picture correct - I don't know - but according to that, in the green connector...

Pin 1 = 12V (always powered on)
Pin 2 = 12V (only powered on when the key is on)

Even with a diagram it is up to you to CHECK these pins - and - decide how you want to power the device: Only when the stereo is on (makes the most sense to me), or all the time (don't see the point if there's no audio happening).

So I would make 100% certain of two things:

1. That the yellow wire IS definitely for power. (This I can't help you with without pulling the device apart in person.)

2. Which pin on the stereo you want to tap for power.

If the yellow wire definitely is for power, then you don't even need a diagram. In fact, I wouldn't trust one anyway. What I would do instead (or to at least check if any diagram were correct) is:

Put a multimeter on DC volts (20V range usually), put one probe to the stereo earth (or car body), and the other probe on each pin on the back of the stereo one at a time, until you find either:

a. A pin that is live all the time, even when you turn the stereo off. (If the link I gave is correct, that will be pin 1.)

b. A pin that is live only when the key is on ACC and the stereo is turned on. If the link is accurate, pin 2.)
