I've been fitting a Blaupunkt Melbourne SD to my '04 Fabia vRS. I had a couple of issue during installation with remote locking (see this discussion)- anyway those were resolved. I didn't however put the powered aerial convertor back in - FM seemed OK. It was only next day when I tried 5live that I figured the aerial convertor is just neded for MW (is that correct?). So I put the convertor back in and replaced wired the blue lead to the aerial into the brown socket coming from the Fabia - in place of the existing blue lead.

Although this seemed to work last night I noticed two problems with this this morning - 1) I got no sound from any source until I disconnected the blue lead

2) My front left speaker isn't working

As you can maybe tell I don't have much experience in this area! Any advice you can share before I screw things up properly will be welcome...

I guess that I need to leave the original blue connected and somehow also click the aerial blue lead onto this?? Is this correct.

Appreciate all comments...

Thanks,

Andy

I've not read the other thread but I'm assuming you've swapped the two live wires over to fix your Central Locking problem.

The Blue lead that powers the Amplifier would normally be connected where the White/Blue is on the Black plug in the car. To remove it you'll need to slide out the locking tab on the plug and then using a paper clip (Folded and pushed into the open end of the plug) release the terminal and tape it back out of the way. Insert your Blue into this and replace the locking tab.

The remote locking issue was actually fixed by not using the ISO connectors that I had bought - by just plugging straight in it worked OK and the power seemed OK also - worked with ignition off.

I tried plugging the blue radio booster wire into the blue/white lead on ISO block A (black) didn't help but plugging it into the Blue/Black opposite did - MW works. However now the unit doesn't work with the ingition off(??). Even when I changed the leads back to how they were...which seems very strange to me. I've not swapped any permanent and ingition leads at the moment. Has the unit somehow "learned" something about the power supply? Can that be changed by some sequence of powering on and off the unit with/without the ignition??

I've read that "swapping the red and yellow leads" changes the power so that it works with ignition off - I don't have a red or yellow lead connecting into ISO connector A though - can anyone advise what leads I should swap (if any!)

The wires I have connecting to the pins on this diagram are

1 - white/purple

2 - blank

3 - white/grey

4 - red/brown

5- blue/black

6 - blue/white

7 - blue/black

8 - brown

the link above suggests that swapping 4 and 7 are the most likely - is that right??

Thanks,

Andy

Also - if the unit is on and I remove cut the ingition and remove the key the screen and blue spot power button flicker - periodic pulse

Bit the bullet and swapped 4 and 7 as described above - seems to have sorted me out. Now unit powers on when ingition off, stays on the ingnition turned off but turns unit off when key removed.

Radio works on MW with aerial attached to 5 above.

You can't just go randomly swapping wires around. You need to compare the pinouts on the new radio with what is in the car.

This is what you will have in the car -

8 Pin Multi Connector Black

1 - 'Gala' function - Volume Adaptation

2 - Mute - Telephone Mode

3 - Self Diagnosis - K wire

4 - Connection for Ignition Key Controlled On/Off

5 - Terminal 30 - Battery Positive (not assigned to Symphony)

6 - Terminal 58b - Illumination

7 - Terminal 30 - Battery Positive

8 - Terminal 31 - Ground

If you look at your fitting instructions or Page 165 of this - http://fe0wap79.bosch.de/intershoproot/files/serviceDocuments/7647533310001_EA_GB.pdf

You will see that the connection I told you to make by removing the White/Blue from Pin 5 and taping it back onto the car loom will free up the slot for the antenna to connect to the new radio pin 5 marked Aut Antenna (Electrical Aerial). This is used because when the HU is powered up it supplies 12v to Pin 5 and thus to the amplifier.

You also need to swap pins 4 and 7, as you will note that pin 4 on the car is switched live and Pin 4 on the new HU is permanant Live. The same follows with Pin 7.

Thanks - I'm sorted now - I had blue/black in 5 though not blue/white. Plugging aerial into blue/black wasn't entirely random - got some advice offline suggesting pin 5.
