12V (Key In) - Ignition Connection Location?

[pennywise]

Hi,

I'm installing an aftermarket head unit, I have removed the original radio and can see that this has a constant 12V supply but it does not have a 12V ignition wire which all aftermarket head units require so that they turn off when the key is removed from the ignition.

Does anyone know how the car's original radio power works since it turns off when key is removed but only has a constant 12V power cable running to it?

Any ideas on where I can run a 12V ignition connection from? (so that key does NOT have to be in glow plugs ON position or engine running position)

I have checked the 12V socket located in the car to see if that would be a good location to feed the ignition supply from but this requires the key to be in the glow plugs ON position so it's not suitable since the power should be there while key is in the ignition but fully turned off.

Any information would be helpful.

Thanks

I messed about with this for ages until I bought the Connects2 lead which solves all these issues, I do understand why people think "I don't need that, I have all the fitting gear" because I thought the same, but you save so much wasted time and money if you simply get the Connects2 lead. I must have spent £50 on rubbish fitting kits when I changed from the OEM unit.

I've recently purchased a Connects2 adaptor for the steering wheel controls to work (CTSST001.2) but as far as I'm aware, this is just for steering wheel controls and doesn't deal with the power issue.

Is the CTSST001.2 the same one that you got or is there some other one that I should have got?

Thanks

Yes this is the one http://www.connects2.co.uk/Product/ProductItem/CTSST001.2

Although it is a bit misleading to call it the steering wheel control, that is in conjunction with the other lead under "Headunit connection lead" if you scroll down on the left.

I had an ISO connector cable from an Ebay fitting kit which gave me the problem of no 12V ignition and once I got the Connects2 lead, all of a sudden no problem.

Oh right, so this is all I need for both the steering wheel controls to work and for the ignition power issue then?

if so that'll be excellent! (I also have the additional "head unit connection" which you mentioned)

Thanks

It is all I needed to connect to the ISO connection on the back of the Philips CED1800BT I fitted

Yep just had a look at yours and has the exact same input requirements at mine (Pioneer FH-X700BT) so I hope it works, just waiting to for the Connects2 adaptor to be delivered and then will test it.

Thanks dude!!!

Okay so I contacted Connects2 customer support and they say the following:

"The CTSST001.2 interface will generate the Ignition voltage required for the aftermarket radio. The ignition is generated from the vehicles CAN signal. This ignition will only be generated when the car is fully on (when the vehicle is running)."

Is this the same for yours?

Because sometimes when waiting/sitting in the car, it would be nice to have the ability to play music without having the car running all the time.

Thanks

They may have misunderstood the question but I say they are wrong, my unit works as long as the key has been turned to the ignition position, you can even return it to the off position and it will continue working. Power is cut when the key is removed.

Mr Saint! I LOVE YOU! you were 100% right!, received the adaptor yesterday, plugged in, everything now works perfect! and power turns on and off exactly as you said! and the steering wheel controls work.

The connects2 customer service guy was wrong and I wouldn't have known it would work if you didn't help me. All this time I was searching for places to tap a 12v ignition source from, was going to take it from the rear windows circuit but now all I need to do is plug in and fit the unit.

I'm also going to run some cables from inside my Pioneer FH-X700BT head unit for AUX and USB from the rear (my unit only has on front).

Thanks again!!!

Thanks, the frustrating thing I found when fitting my head unit was although there are some very useful guides/FAQs that help you in a generic way, for the odds and ends they don't cover there is a phenomenal amount of inaccurate information to be found and an awful lot of things that claim to just plug in that in practice don't work like that.

The Connects2 stuff is an honourable exception to this (even if some support staff don't know it)

The Saint - quick question for you:

Since installation of the connects2 adaptor to enable steering wheel controls, two of the buttons on my steering wheel for UP/DWN folder (when CD or USB is selected as source) or PRESET STATION UP/DWN (when tuner is selected as source) don't work, no response from these two buttons at all.

All the other buttons on the steering wheel work fine but those two don't, can you confirm if it's the same for yours too or do they work on yours?

Thanks in advance!

OK - for me the left button never changes.
Up/Down controls volume
Forward/Back skips forward/back through tracks or moves the radio tuner up or down the frequencies.

The right button took me a while to get used to as you have to cycle through the normal car MFD options until you see "Audio Active" in the dashboard display. Once you have this showing then up and down changes in context with what you are doing so with the radio on it cycles through AM1, AM2, FM1, FM2, FM3 however if I am playing MP3s through the USB interface and press the up button it changes to the radio, I don't think I have ever played a CD but would assume a similar thing happens and again with DVD but I have only played these out of curiosity.
My main use of the right hand buttons is when I have the unit's satnav running as otherwise I would have to switch back to the normal interface.

I think your steering wheel is the newer style one, where as mine is like the one in the following link:

So for mine, all buttons work apart from the two UP and DWN buttons on the left side of that pic

Cant figure out why though, wondering if the connects2 adaptor doesn't support it or if it's the wrong one/faulty...

I would suggest Connects2 support but they didn't cover themselves with glory previously

I've been in touch with Connects2 about the steering wheel control interface adaptor that only half works. After asking me to check a million things, wiring, connections etc, which I all did and provided proof of by sending them photos, voltage readings etc.

The advisor has told me the following:

Hello

It is possible that the interface is faulty but we can not say for certain if it is a faulty interface, it is possible that the data is not correct for those buttons.

Best Regards
---------------------------------------------------

I then went and bought another interface just to double check that the one I have isn't faulty and found the exact same issue again.

I don't understand how they can sell a product that only half works???

So I now have lost money on two Connects2 interface adapters that only do half a job and this isn't because they're faulty, it's because connects2 designed them this way!

Very disappointed with Connects2, I won't be buying their stuff again, thinking about buying this interface adapter instead:
