Thanks for that. I *thought* that would solve the problem, but it just confuses me more.

On my radio looking at it as per the pic in your link, I have no pin at location 3 on the radio (JVC KD-G611) and also the harness adapter I have has its blue lead at location 5. It is going back anyway as the white wire was not crimped in and has come loose and I cannot get the pin out. I'll try that test when I get another adapter. Looks like I'll need to get some bullet connectors as well.

Thanks for the post.

Have a read of this http://www.briskoda....-stereo-wiring/

Almost there !!

Tested all the wiring yesterday and had the mp3 player connected in, all good. Had to swap red and yellow, as without doing that the JVC always forgot what media it was playing when switched off and started at CD. Radio stations were fine though, all remembered.?

Managed to get the cubby hole out eventually. No screws holding it, just some grooves.

My mate is trimming the plate to fit that cubby hole exactly and then all will be offered up and fitted.

Fitted the aerial booster. Tried connecting blue lead from that to blue lead from harness adapter, but did not seem to make any difference to the quality of the radio reception.

So all looking good so far.

Really looking forward to being able to play any CD out of over 500, rather than any CD out of 6.

Glad to hear it's up and running-ish, might be your ariel thats knackered, I think the amp is in the base of the ariel and people on here have had to change them before, http://www.briskoda.net/forums/topic/84690-mk1-vrs-naff-fm-radio-reception-need-help/

You need to connect the blue wire on the booster to a power supply, either use the switched live (yellow or red, whichever one it is), or connect to the output on the HU for an electric aerial - which is usually the connector the blue wire on the harness would plug into.

What you probably did was connect the aerial booster to the OBD socket, so not surprising it didn't work.

Ok, I'll put a m/f bullet connector on each blue line.

No, I just held the two blue wires to make contact. The blue lead from the harness adapter ends in a small female connector, not as large as a female bullet, the factor shop said it was an inline connector and to just crimp the other lead in, but then I would not be easily be able to split the wiring should I need to, so I opted for a bullet connector yo keep it tidy.

I'll test the voltage from blue to earth when I get the plate, otherwise I look at teh red/yellow option.

Thanks again for the replies and link

The blue wire on the original harness connects the factory fit HU to the diagnostics port, so if you connected the signal booster to the car side of the wiring there would be no power supplied.

This leads to the problem where fitting a new HU without adaption of the wiring means that you ended up supplying 12V from the electric aerial (which is what everyone else uses that connector for) straight to the diagnostics socket which has caused quite a few dealers having their expenses computer equipment ruined until the problem was identified.

I should be OK there. The blue lead from the JVC radio is on pin 3 on the bottom section of the radio, looking at it from the rear

1 2 3 4

5 6 7 8

and it is this that ends in an inline connector alone on its own, so it is not going anywhere near the diagnostic line at tthe car end.

This is the one I bought, but from ebay, the part number being the same

However when I next connect it up, I'll check that it actually does put out some voltage for the aerial booster. I don't want to be whipping this lot in and out all the time, so will get it right first time.

Fair enough, break out the circuit tester.

All done

Thanks to all who have chipped in with advice and warnings.

The blue lead from the radio is now connected to the aerial booster as advised.

Red and Yellow wires swapped over via the harness I purchased.

Had a little trouble fitting everything in as my unit requires a small black box adapter for the mp3 player and little room at the back of the radio. Manged to fit this into the cubby hole below by widening the holes in the cubby hole top, so now it sits behind the mp3 player faceplate

End is result is as below..looking forward to using it starting next week back and fro to work.

Almost forgot.:-(

Forgot to take out the CD cartridge from the CD player, before doing all this. Any way to

a) Remove the CD changer.? It is hard wired by what I have seen so far. I took the small plate off the back, but the wires just disappear into the unit.

Get the CD cartridge out to get my Cds back.?

TIA

You can remove the changer from the car and dismantle it, I had to do this when my changer went kamikaze and completely jammed the cartridge inside the changer. But you might knacker it in the process. I suppose if you can work out which wires are which you could supply 12v to it and an earth then eject the cartridge properly.

With everything so tidy in the car I really expected a plug of some sort, very much like the plug that goes in the back of the HU.

All my Cds are ripped, so no great urgency and I really do not want to remove the radio etc after all the effort that it took to get it in.

Ah well, you live and learn.

Thinking about it, I'm sure my changer had a short length of wire terminating with a multi pin plug, I will try and have a look at it later, it's in the shed at home.

Cheers,

I haven't looked behind the trim. I just unscrewed the changer from the bracket and expected a plug at the back, but it seems hard wired plus a wire clamp to prevent it getting pulled out, and the wires just disappear into the unit.

Just been and checked in the shed. The wire coming out of the changer is about 1 foot long and terminates with a multi pin plug.

Thanks very much for doing that. Guess the trim is coming off.

At least it should make it easier to apply 12v to the changer and get that cartridge out.

Is your car a hatchback or an estate?

Hatch

Is your car a hatchback or an estate?

thought so, in the estate the changer hides behind the trim and when you open the little door to access it you can see all the associated wiring and get to the plug easily.

At least I know there is a plug somewhere behind there.

Now need a fine day on the weekend. It's been bucketing down here today and I picked up on the problem with the hatch letting water in when lifting it after it has rained.

Shame you're far away wouldn't mind letting you plug your changer into my car to get the discs out

Sent from my Galaxy S2 not a Crapple!

Well, it is the thought that counts.

I'll work something out. As I mentioned before, I do not use my CDs much at all now they are all ripped. In fact that was probably the first time in over 5 years.

Thanks to your post, I found the plug encased in a foam pocket with cable ties. Changer is now out including the holding plate. One bolt missing from that.? Thanks for taking the time to do that.

IIRC on the estate one or more of the bolts which holds the braket for the cd changer are actually the bolts which hold the bumper on. However I think the hatchback is different.

Yes, the missing bolt was toward the front and mine seems to far away to be related to the bumper.
