Symphony II with Sat Nav

[var679]

Hi,

recently joined the forum and after some advice please.

I have a 54 a4 avant sport. The car has a symphony II with Bose and sat nav. The Navigation is displayed via the centre information display.

The question I have is re the fitting of a parrot kit.

I have fitted the kit using the Tel + & - input, pin 3&4 on the rear of the Symphony II head unit. The mute function is wired via pin 1. Power is all in place and the system works fine, until I turn the ignition on.

When the ignition is off, the stereo mutes and sound can be head from the speakers. When I turn the ignition on, the mic still operates but no sound is available through the speakers.

If I disconnect the NAV inputs from the same multi plug (Nav + & -, the parrot works fine with the ignition on.

The label of the Symphony II only shows the NAV inputs and not the tel. I have read that a 5k resistor is required to the + tel line due to input voltage, but would this cause this issue, should I be connecting the parrot through the Nav system which then feeds the Symphony unit?

Have posted this very same thread on other forums as urgent advice needed, any advice would be much appreciated

thanks

Hiya

Did anyone find a solution to this problem?

I am having very simular issue with parrot 3200LS.

I have 2004 A3 with syphaney full Bose and the Cd Sat Nav (only has small screen between speed and rev counter.

If i unplug the 3 nav cables going into the head unit the handsfree kit works a treat, it will mute the radio with "phone" in the display
If I then plug the Nav cables back in the headunit still mutes the sound and displayes phone but i cannot hear anything.

Any Idea's anyone? maybe i need to connect the Phone audio to the nav which then goes to headunit?

Any ideas are much apriciated

ok people after alot of head banging and looking at circuit diagrams i figured out how to get the phone audio through the stereo.
You need to connect the mute cable to both the head unit and the nav unit in the boot. on the stereo it goes into pin 1 on the vertical connector and on the nav unit it is labled which pin to use.

You then need to run the audio + and - back to the Nav unit in the boot and connect to the 2 pins show on the diagram ontop of the nav unit (i can't remember the pin numbers). I have now sucsessfuly connected my parrot 3200 LS to my bose symphony headunit and works great at higher speeds the audio level can be a little be quiet but apart from that it works great.

guy's,

this is exactly the problem I had with the NAV connected. Posted this on a couple of places, got an responce that said to connect through the nav unit in the back. I then got another responce from an auto leads dude who stated to go through the head unit in a certain way. Basically, I thought I'd try the second to save running wires to the back. It worked, but the quality is absolutly pants!!!, very quite and appears to be low on the mic. I've also now started to drop the mic, but can hear everything.

The last post is spot on, can't find the reply that gave the actual pins to connect to, but would suggest this is defo the way.
