Citroen Dispatch stereo wiring

Tiree · 2013-09-21 19:45:18

I decided to replace the original Citroen branded factory-fitted stereo in my Dispatch (2006).

I went for the Pioneer MVH-150Ui - but it uses the universal ISO connector so this story should help anyone trying to fit an after market stereo.

In short - swapping these over is a breeze - but one major issue cropped up.

After installation - the new stereo would not remember any settings, radio stations or anything else.

Every time I switched off the ignition - all the settings were lost.

Now, I knew that all the connections had fitted fine - and I knew that the factory-fitted stereo retained all its settings fine.

Car stereos take two power supplies: one is a switched 12v supply which is activated when you turn the ignition on; the other is a constant 12v supply which helps the stereo keep all its setting in memory.

So it seemed like the constant 12v supply was missing.

In actual fact - Citroen, on this model and some other Citroen cars, decided to break from the ISO standard and swap two of the connectors.

Here's the ISO 10487 standard connector as it should be:

So Citroen have (in their wisdom!) swapped connectors 4 and 7 on the ISO A connector.

Once I swapped over the red (switched 12v) and yellow (constant 12v) cables going into my stereo head unit - the problem was solved smile

Now .. to replace these factory speakers ....

Hope that saves someone some time!

PS - I'm not sure if this fix applies to the Peugeot Expert and Fiat Scudo.

On a similar subject - does anyone have a wiring diagram for the dispatch / expert / scudo? I'm replacing the front speakers and can't work out which wires are positive / negative.

Both are yellow, one bright, one dull.

Anyone any ideas?

I've tried wiring them both ways but to be honest I'm struggling to hear much of a difference.

All the same I'd like to get it right!

At the moment I think the bright yellow is -ve and the dull yellow is +ve.

Thanks for any help!

FascinationStreet -

I think you should be able to tell this from the connector at the back of your stereo.

The ISO connector in Tiree's original post shows what wires go where in the connector.

Whatever cables are in B5 and B7 should be positive, B6 and B8 are negative.

Definitely worth getting right as you say cos bass response will be affected if the speakers are out of phase mad

I'd like a wiring diagram for my Dispatch too right enough! Anyone?

For the record - this page gives a good bit of info about the stereo connectors used in the 2006 Dispatch I have:

Again - sorry - not sure if the Expert and Scudo differ.

There are wiring diagrams included in the Scudo manuals we recently uploaded right here:

Hi Tiree,

Got my radio in in the end but now I'm looking to replace the speakers same as you. Do you have any tips on that or did you find that any old car speakers worked?

Cheers!

Craig

Tiree · 2015-02-26 16:00:22

Hey Craig ..

Glad to hear Radio's in!

I bought pretty cheap (£20 i think) 6.5" affairs from Halfords - which (predictably enough) I now want to replace.

However - worth noting that my front door panels rattle badly as soon as any sort of reasonable bass goes through them.

So my plan is to get a modest boxed sub and fit it in the void under the middle seat - then fit new half-decent 6.5" speakers in the doors, but cut off the bass going to them.

That's the plan at least.

For starters though, yeah standard speakers went in OK for me.

Keep us posted!

Tiree · 2015-02-26 16:04:08

PS - just realised you're in a 2009 which may take a different size of speaker (although a quick ebay search suggests they're the same) and also may have less rattly door panels!

Hello folks. Just got an 06 Dispatch. Love it. But The CD didnt work so I swapped it for a Kenwood CD/radio from my old Berlingo. Problems as above: each start up have to reset. But before I try and fettle it up with constant 12v rejig, does anyone know if its possible to add an iPod connection through the ISO connector or do I have to get into the innards of the CD/radio? Any advice would be much appreciated. (btw, some of the camper conversions on this forum are very impressive)

I have the exact same problem Tiree, would try the solution of swapping the cables in my Peugeot 2004 Expert, but being an electronic ignoramus- if they aren't the same, am I going to blow up my new stereo?

One wire is always live and the other works with the ignition. Your stereo should have a label stuck to it telling you what is live and whats ignition. Most i have installed have been yellow ignition and red live funny enough but find out first. All you will do if they were the wrong way round is the radio will not go off with the ignition and it wont remember radio stations. Buy a multi meter if unsure.

Gareth · 2016-01-30 10:25:58

Could anyone kindly tell me the steps to wire in this sub? I know it is probably simple. I have a 2002 Expert. Guess I just need to run off the two box connectors, 4 pin and 6pin.

Would I wire it in as a "rear" set of speakers so I could control the volume sent to it?

tezla7 · 2016-01-30 18:33:03

Right so, unplugged the stereo and there's no battery connection that switches off with the ignition, only the permanent connection from the battery. And we volt tested it and it's 12V. So, the right cable is connected, otherwise the radio wouldn't even switch on. It seems that the stereo remembers its connections for a minute or two, but any longer, three or four minutes switched off and it's reset itself. Strange, must be something to do with the battery maybe.

Well that's odd.

There should definitely be two power cables, my 2006 Dispatch has one red (ignition switched 12v) and one yellow (constant from battery 12v). All head units I've ever dealt with require both. The one cable (from the battery) you've found is likely feeding into the ignition switched socket on the head unit (see original post on connectors 4 and 7 on the ISO A connector ^). This means that even though the wire has a constant supply, it's not feeding into the constant supply socket so it won't have constant power.

Need to find that other wire!

Then swap them over.

tezla7 · 2016-01-30 21:03:52

Yeah, it is weird. It reads 12V on the multimeter when the engine is switched off and goes into the correct connector described in the head unit manual and in the vehicle handbook. The cables were both pink, no red or yellow. Like you say, maybe it needs both the battery and permanent, but at the moment it's only got the permanent not the battery- nothing in the connectors below 6. Could be the radio, could be the fact it's only got the one power source, could be something iffy with the battery connection.

tezla7 · 2016-01-30 21:12:46

The radio doesn't switch on when the ignition and battery is switched off- so surely that means the wrong cable is connected like you say, and I need to find this hidden permanent ACC+ cable.

The radio should not switch on if ignition is off. So if yours will only work when ignition is on then that live ignition wire is correct. You have a cut or missing wire (Yellow i think) have a good root about as some other owner may have used it for an auxiliary or fag lighter or whatever. If need be take a feed from your fag lighter as i am sure that is on the ignition but do that as a last resort.
