Hi

Apologies if this has been asked before but logic prevailing I don't understand...

Swapped my standard kenwood tape player over for a kenwood kdc 3041 (another forum member said this works fine so I bought this one), just simply plugged it in with the existing iso connector/adapter.

New headunit works fine radio/sound etc., but the steering wheel volume control, cd track change and other button has stopped working completely.

Thinking I had bought a dud new headunit I reconnected the original headunit which also now doesn't work with the steering wheel control.

What the hell has happened?

Thanks in advance.

Hi you could try battery (disconnect 30 mins) reset with your old unit and see if it works? could try with new unit as well, but i think that they have to be programed via a T4 computer, not 100% sure but somebody will be along who knows, Ste

?? infra red w.t.?? . kenwood krc-391 was my original headunit got to see if this has infra then ?

i presume then my new head unit would have to be infra red compatible if this was the case

http://forums.mg-rover.org/forumdisplay.php?f=90 = found this link, but thought infra red only applies to > 2001 ? Mine was made in dec 02.

Also call me a clown, where is the eye brow exactly ? - above, below, behind the head unit?

don't know if i am allowed to link to another forum apologies if i am not, also found this : -

http://www.the75andztclub.co.uk/forum/showthread.php?p=108256 =

I looked through the kenwood 391 manual and it says nothing about infra red.

http://google.mg-rover.org/showthread.php?p=2752532 = another post ??

HELP !

It's what unit was originally fitted rather than the date, if you have a KRC 391, it will be the infra-red system. Have a look at the bracket behind the head unit (where the rubber spigot on the back fits in) There is a box bolted to it with a lead with an LED on the end, which should be clipped to the underside of the eyebrow.
The eyebrow is the curved part above the shelf of the facia, the same colour as the dash.

ok crystal clear what the eyebrow is now ! :) understood thanks.

so in theory should the swap of a krc 391 to a kdc 3041 should of worked with no drama ?

Have I probably jogged/disconnected something in the removal of the head unit.

I presume the little sensor under the eyebrow is a thin little cable just dangling ?

Yes the thin cable as it got what looks like a LED on the end? also is this your new unit http://www.kenwood.eu/products/car/receivers/cd/KDC-W3041AY/details/ if so it comes with IR option, weather its compatible with the steering controls? Steve

Hi

Yes thats the exact head unit i've got ! :)

so it should work then ?
You will have to read the manual on how to set up the IR and try to find out if its compatible with the old steering controls? if not are they obtainable? could be just a simple wiring job, you will have to check the wiring diagrams for the steering controls and see if the wiring configuration match's up with your new unit wiring, could just one simple wire to move? now you have some homework to do :hysteria:Steve

It will be compatible, with the hard wired systems adapter leads are needed to convert the MGR resistances to ones recognised by the different head units. With the ZT Kenwood system, the box on the bracket converts the MGR system to the Kenwood I.R. system, so any I.R.remote control Kenwood unit will work.

Tried to find the infra red lead under the eyebrow - nothing there.

Looked all over where the car stereo cables are nothing.

Retried both headunits - still no steering wheel control.

Rang specialist car stereo shop - they did not have a clue.

Does the steering wheel have a fuse on the fuse board or not ?

So who can help me out of a jam for some cash, prepared to travel 30 mins from near junc 11 m25?

The infra-red interface box is (should be ?) bolted to the bracket behind the head unit, it will have 3 cables (Blue/Purple, Light Green/White & Black), and a lead with the LED on the end. The lead may have dropped down the back of the centre console, it needs to be brought through to the eyebrow.

The plot thickens..

Found a loose lead - Green and red colour lead disconnected with no crimp and bare wire... ???

And another twist...

Blue (5amp fuse holder) and red cable (1amp) have been connected to 2 fuse holders which are completely separate to the normal rover/mg stereo blocks/isos.. ?? w.t is this ???

Put my hand right right down the back of the centre console and can't find any other wires.

Suspecting someone at some stage has converted the infra red may of converted this to hard wired.

RayKay sorry to sound cheeky but u seem to know your stuff, any chance of u having a look if I drove wherever at your convenience ? if not no probs.

If the Green/Red is in pin 1 of the power ISO connector, it's for phone mute input for the Symphony unit.

Have you found the box that should be bolted to the bracket, if the controls worked before, it must be there somewhere.
 
#23 ·
green/red is plugged in no where - it's literally dangling there. i also have a nokia hands free kit that i don't use.

can't find the box... which is making me suspect that someone has converted it to hard wired.

???

seriously all out of ideas and local car stereo shop who has done feature cars for car shows etc are not interested not clued up enough on the infra red ...
 
#24 ·
One end of the Green/Red cable will free and be dangling, it's the other end that may be in pin 1.

It won't have been converted as your old unit uses the infra-red system, the box has got to be there.......... somewhere.

The odd cables could have been for a phone kit, the stereo cables are a common place to connect it.

well it looks like i will be rummaging around for this pain the *rse infra red box tomorrow.

It's so bluddy irritating as I've got this new headunit ready to go in and I am quite stubborn so maybe I will get to the bottom of this.

Thanks for all replies but I could really do with someone giving me a hand in person - can't believe the car stereo specialist didn't want to know... I think I am looking for a needle in a haystack.

Should I give up on this ??

No car stereo engineer seems to be capable of understanding/having experience of a rover 75 / mg zt..

No grey cable found for this infra lead I am supposed to have...

Perplexed and driving around with no sounds in the hope that someone round my neck of the woods can solve this puzzle for some cash..

Hi have a look at this site http://www.incartec.co.uk/ select the instructions tab, look for the rover 75/ZT it will give you some wiring diagrams to look at, if no luck with diagrams give them a ring, I'm sure they will sort you out, so don't give up just yet mate, Steve
 
#29 ·
If you were nearer i'd give you a hand no problem, but alas no.

Just to confirm:

You don't have the grey cable coming from the infra-red box,
You don't have the infra-red box,
You don't have any spare cables for the IR box.

Yes?

Do you have any spare wires, or the bracket for the IR box? Your car came with the OEM Kenwood and it worked, yes?

Update close but no cigar so far..

Found the holy grail grey cable and yes it is indeed behind the eyebrow !!!, managed to find it (I know to the rest of u on here it should be a doddle this but to me it's been a mission).

Have not removed the eyebrow yet, but 100% have found the grey cable, but can't trace where the grey cable goes back too - it's goes towards the right of where the stereo would be .

The grey cable seems fixed somewhere behind the eyebrow, so can I just pull it with force and it will be ok to point it at the headunit?

Again sorry to for boring everyone on here.

And yes 100% the steering control was working with oem kenwood headunit, but now will not work with neither head unit..

Don't pull on the cable - you might break it.

Just remove the eyebrow / stereo and have a reach around to see if you can get it out nicely.

Removing the eyebrow is a 30 second job... pop off the plastic cover underneath, and then undo two screws and it pulls out.

Hi Jakg

Massive thanks for the replies, i know this has been drawn out process and really easy for others but I am getting there ! ........ :)

looked underneath the eye brow i can see two holes/flaps - which i presume i depress with a flat head screw driver, then this should pop off and i can then unscrew and get to the holy grail - the grey cable !!!

Just a quick ? - the cable should hide behind the eyebrow i presume and remain there on the passenger side once I've tried it again.

If it doesn't work once I've got there I presume new cable to i.r box - if so is it easy to fit a new one?

Thanks !

Now you have found the grey cable (don't go pulling it) its all to do with the positioning of the cable, if you look at the plastic under trim from the eyebrow, you will see two small holes!! if the end of the cable (the bit what looks like a LED) is not positioned properly into one of these holes,
none of your head units will work with the steering wheel controls.

This sends a signal to your head unit in simple terms, if its positioned properly and not obstructed in anyway it should work, if you have a look at the wiring diagrams on the website i posted in my last post, it tells you how it should be wired up and how you should test the circuit before you connect your head unit.

My advice, refit your old head unit and try it, now you've found the grey cable, this will tell you that the wiring is OK or if you do need a new cable? i posted this information as well.

I don't know where you live (i know your down south) maybe you could have a trip to the guys who know what they are doing at http://www.incartec.co.uk/ Ste

I doubt it's hard to fit a new one, but I must confess I dont know - looks like a bolt and a connector to me.

The cable should go in the passenger side hole... might take a little "adjustment" to work with the Kenwood units (the newer the model, the more the fascia seems to stick out and the more of a pain it is to get this ass-backward system working!)
