Retro fit nav with T.V, working but no nav sound!!

[goldysingh]

Hi all, firstly what a great web site, i successfully completed a retro fit nav system with tv on my e38 with help from the manuals and info on this site.

I have managed to install a complete nav system with t.v system but have encountered a small problem, NO SOUND!!

I have sound from my cd changer but no sound from my t.v or nav system, i think i know what the issue is but need some assistance.

The loom which i have installed in my car came out an accident damaged 1998 car, mine is a 1997. The loom fits perfectly and all of the components works well. I have a normal bmw amp (non DSP), the speaker wires that come out of amp have two bunches of wires, a blue bunch and a yellow bunch, total of 8 sets of 2 speaker wires (8 outputs in total) but my existing loom for the speakers at the front of my car only has 4 outputs.

does anybody know what colour the wires coming from the amp for the tv and nav system? I can hear a slight noise coming from the speakers when the nav system when it tries to talk..but no voices!!

please help!

Thanks

:xoutpost:

consider posting this problem in the e53 forum. not many people go into this forum.

also try the BSW electronics forum where usually the vendors answer questions fairly quickly

Try dropping a PM to King or JPuma. Both have successfully done a nav retrofit and have a wealth of knowledge on this topic.

All wiring colours, pinouts, and signal names are shown in the wiring diagram in the rear of the retro-fit instructions.

You can reference any retro-fit instructions - E46, E38 or E39 - they are basically the same.
Here's a copy of E38 instructions:

You need to make sure your radio output from the tuner module is connected to the DSP amp.
You need to make sure the audio lines from the TV tuner are connected to the radio module
You need to make sure the audio lines from the nav are conencted to the TV tuner

Thanks for that Jochen, i have looked at the retro fit instructions but im still confused..there are so many more speaker wires coming from the new loom than there are connection for them from my existing plug in the front console where the old stereo was..do all of the wires need connecting? is my car missing speakers!!?? do you have a picture of how they should be connected at all? thanks again..

It is possible your car never had the full complement of speakers fitted.

In an E39 5-series, there were 6 (radio) and 10 (hifi)-speaker packages.
On the 6-speaker packages you had front door tweeter and bass, but no mid. So there was no speaker fitted behind the mid-range grill. ie: grill was there, but nothing behind it.
In the rear, a full-range speaker was fitted in the parcel tray woofer cavity, and no tweeters in the rear doors.
I thouigh E38 always had all 10 speakers (hifi), with 12 as an option (top-hifi) when the DSP amp was fitted. But maybe you only had 6.

Let's look at the WDS for the wiring for you:

All E38s with non-DSP Amplifier have the following speaker wiring colours:

Front left tweeter: pos =yellow/green, neg = yellow/brown
Front left midrange: pos = yellow/white, neg = yellow/brown
Front left bass: pos = yellow/red, neg = yellow/brown
Front right tweeter: pos =blue/green, neg = blue/brown
Front right midrange: pos = blue/white, neg = blue/brown
Front right bass: pos = blue/red, neg = blue/brown

Rear speakers:
Left tweeter (in door): pos = yellow/black, neg = yellow/green
Left woofer (parcel tray): pos = yellow/violet, neg = yellow/green
Right tweeter (in door): pos = blue/black, neg = blue/green
Right woofer (parcel tray): pos = blue/violet, neg = blue/green

Spot the logic:
Left = yellow, Right = blue
Front: Tweeter = green, mid = white, bass = red
Rear: Tweeter = black, woofer = violet

All speaker wires are twisted into their own pairs.

The wiring from the radio to the amplifier is different for DSP and non-DSP.
On DSP cars, the radio outputs are wired from the front speaker outputs only
This means only 4 wires for sound from radio to DSP amp:
Front left pos, radio pin 1, yellow/red
Front left neg, radio pin 8, brown/orange
Front right pos, radio pin 2, blue/red
Front right neg, radio pin 11, brown/orange

The DSP amp takes care of the fader/balance functions

Without DSP, the radio also has the rear outputs connected (front wiring is same as for DSP):
Rear left pos, radio pin 3, yellow/black
Rear left neg, radio pin 12, brown/orange
Rear right pos, radio pin 6, blue/black
Rear neg, radio pin 14, brown/orange

Without DSP, the amp needs to be switched on by the radio, so check your amp switch-on signal:
Radio pin 16, white. 0V when radio off, +12V when radio on.
With a nav system, the amp is on most of the time.

Check your loom, see if you have the front and rear wires from the radio to the DSP amp. If you have DSP loom and non-DSP amp, you won't get the rear speakers going.

Check your wires and report what you have.
All wire colours are unique, by reporting your wiring colours i will know exactly what they are.

Hi Jichen, great help on the write up..
ok, I have opened up my door cards and have found one speaker behind the grill and one tweeter, so in total i have 4 speakers in the front, in the rear i only have one speaker on either side behind the grill and no tweeter, so in total i have 6 speakers.
The wiring for the speakers from the old plug are as follows...

yellow+red twisted with yellow+brown = Front left bass
yellow+white twisted with yellow+brown = Front left mid range??
Thats all the yellow wiring i have.

blue+red twisted with blue+brown = Front right bass
blue+white twisted with blue+brown = Front right mid range??
Thats all the blue wiring i have.

I cant understand this! i should have some more wires for the tweeters surely??

pic of the wiring..

the new loom which I have installed has the following speaker wires,

Blue+red twisted with blue+brown
Blue+purple twisted with blue+brown
Blue+white twisted with blue+brown
black+white twsted with black+brown
Yellow+red twisted with yellow+brown
Yellow+green twisted with yellow+brown
Yellow+white twisted with yellow+brown
Black+white twisted with Black+white


any ideas what are the black wires for??

I dont have a dsp amp, just a standard bmw amp, the sound from the cd changer works fine, i just dont get any sound from the sat nav, i have double checked all connections and they seem to be fine. I am certain the issue lies with the speaker wiring.

How would i compensate for the extra speaker wires? i have tried connecting the extra wires with the currrent wires but still no joy..

Thanks again..
