Please anyone, I am getting desparete in this subject and already broke the CD changer playing with the radio connections. {** Never leave CDs inside the Symphony II before unplugging it.}

Short story: (not so short after all)
I have an Audi A4 04 Symphony II (BOSE) and my goal is to integrate the Parrot MK 6000 to the head unit so I can get sound through ALL the speakers (to take advantage of A2DP).

Now the question is, how can this be done? I have google, mp3car, and many other forumns for this answer and even call some professionals on this and they say there is not something that could get this done.

I understand the difficulties with the Audi's BOSE system, but I can't believe this is undoable.

My current state. I tap into the (+) signals of line out in the HU, and connect the (-) lines to the common ground. That's when I learn about level output among other problems with this configuration where I can get only sound in the front speakers.

Please any help let me know.

Thanks in Advance

** Another option could be changing the HU for an aftermarket one which fit the BOSE amp and speakers nicely. Still requierment will be having bluetooth to play a2dp and receive calls. Doesn't need navigation, but any recommendations are welcome. I just want to get over this.

A lot of the Audi HU's in europe ("concert" etc) have a input for telephone. (tel+ and tel-)

I don't know if the parrot also has a line out, perhaps you could connect that to the tel in of the HU?

perhaps this might help:

the parrot should have an adapter harness that you can buy and just plug in to the existing harness. The wiring diagram on parrot's site shows an iso adapter.

When I installed my mk6000 in my truck I just used the iso cable that connected directly to the factory head unit.

T4Roger

The standard harness is only for "standard"radio's, the Bose system does not have speaker chanel, instead it has line-out, IF the parrot works with the standard harness (with adaptercable) it will not service every speaker. Probably it will not even mute every speaker (this can be solved by connecting the mute-cable to the mute-terminal of the HU)

hyperplus

T4Roger you are in the right line of thought.

The problem is that I want A2DP from the Parrot MK6000 to work through the radio. The only way I see this possible is to connect the parrot to AUX channel in the Symphony II using Speaker Wire to RCA (note you need something like Blitzsafe, CarAUX, among others). But even with that idea I will still be counting in my adapter to transform the parrots signal to the correct power before entering the HU.

After further research I am thinking of replacing the HU. Easier / not that cheap / but since I broke the cd changer it might be a good idea.

Anyone knows if any radio will be compatible with my bose amp / speaker system? If not what should I look for?

thanks

hyperplus

Anyone knows if is possible to run phone through all speakers amplified with retrofitting a Symphony II+ into my B6 Bose system?

Thanks

Doable or Not? MK6000 - Symphony II/II+ & BOSE

Please let me know your thoughts if this will work or what else should I get.

My goal is to get BOSE amplified sound through all the speakers using the Parrot MK6000 with the Symphony II or II+ head unit.

I think this could be done using a connector like BlitzSafe, CarAux, etc. to send the signal as AUX. In such a case I guess I need a Speaker Wire to RCA connector for the parrot kit. Do I need a Hi-Lo converter as well for the Parrot?

The other questions I have are:
the Symphony II and II+ have the same connector at the back?
the Symphony II+ will not be able to use the phone through all speakers neither?
going the AUX route is it possible to connect the Parrt (left/right+front/rear) wires to the AUX, will this be better than just sending Stereo signal?

Thanks

I thought I will have a result by this week, but I found another problem. If anyone knows what to try let me know, but I really think I am out of luck.

My current problem is the radio stays ON in Phone mode even after shutting down the car.

So I try connecting my Parrot MK6000 to the Symphony II (BOSE) radio and I notice the radio stays in “Phone” mode even when I shut down the car. This is a problem because it will drain my battery. I think is due to the Mute pin in the radio is reading 5 volts. Probably that is powering the Parrot.

Also when the car electrical is ON, the parrot works OK. And I try switching the red line with the orange line, but no luck.

Please any help will be appreciated.

Are you sure the mute-lead of the parrot is connected to the right pin of the HU?

The mute is pulled down to ground if the parrot wants to mute the radio.

The red wire with fuse needs to be the permanent power, the orange one switched.

Also check if the black wire gets good ground, if not the unit can search ground through other wires and connected devices.

Do I understand correctly that the sound over the speakers -problem has been solved?

Perhaps a small relay switched bij the parrots mutecable and connecting ground to the mute-pin of the HU can solve your current problem.

(coil of relay one side to power 12 V, the other side to the mute cable of the parrot; The connections of the switch one to ground, the other to the mute-pin of the HU)

If nothing else works, you can try (first check at the Audi-servicepoint if it won't hurt the HU) to use a pull-up resistor. This is a relative high-ohm resistor you connect between 12V powerline and the mute, if the mute is not switched by the parrot, there will be a 12 volt signal to the mute lead, making sure the HU does not think there is a call in process.

THANKS FOR YOUR REPLY. I WILL WRITE IN CAPS TO ANSWER YOU QUESTIONS.

YES. ALSO ABOVE IS A LINK TO OUR CARS WIRE DIAGRAM.

The mute is pulled down to ground if the parrot wants to mute the radio.
I AM A LITTLE CONFUSE HERE, BUT THESE ARE THE VOLTAGE READS I MADE.
THE MK6000 (YELLOW MUTE CABLE) READS 0 VOLTS WHILE NOT TRANSMITING AND AROUND 12 VOLTS WHILE IN USE.
THE SYMPHONY II RADIO READS 5 VOLTS WHILE NOT IN PHONE MODE.
WHEN THE CAR IS ON THE PARROT MUTES THE RADIO FINE.
WHEN THE CAR IS OFF THE RADIO GOES/STAYS IN PHONE MODE.

The red wire with fuse needs to be the permanent power, the orange one switched.
RED WAS CONNECTED TO POSITIVE IN RADIO (WHICH READ 12 VOLTS ALWAYS).
ORANGE I TRY THE FUSE BOX AND THE PIN NEXT TO COM.
ALSO I TRY SWITCHING CABLE CONNECTIONS FOR ORANGE-RED

Also check if the black wire gets good ground, if not the unit can search ground through other wires and connected devices.
BLACK WAS CONNECTED TO THE CAR GROUND. I RUN A CABLE ALL THE WAY THROUGH THE CONSOLE. (I DON'T LIKE JUST GETTING A SCREW).

Do I understand correctly that the sound over the speakers -problem has been solved?
AFTER I FOUND THIS, I HAVEN'T GO FOR THE SOUND STEP. BUT ACCORDING TO AUTO-TOYS IT SHOULD WORK (STEREO WIRE OUT, TO RCA CONVERTER, HI-LO, AUX CONNECTION)

Perhaps a small relay switched bij the parrots mutecable and connecting ground to the mute-pin of the HU can solve your current problem.
WHAT IS A BIJ? I AM STARTING TO LEARN ABOUT RELAYS. ANY GOOD LINK? I UNDERSTAND THE BASIC IDEA, BUT I DONT KNOW WHAT SHOULD I NEED.

(coil of relay one side to power 12 V, the other side to the mute cable of the parrot; The connections of the switch one to ground, the other to the mute-pin of the HU)
I GUESS THIS IS RELATED TO THE RELAY; ALSO I TRY CONNECTING THE PARROT MUTE WIRE, RADIO MUTE PIN, AND ALARM GROUND TOGETHER. MY HOPE WAS THE ALARM GROUND WILL BE STRONGER AND THE 5 VOLTS FROM THE MUT WONT RUN TO THE PARROT, BUT SEEMS I WAS MISTAKEN.

If nothing else works, you can try (first check at the Audi-servicepoint if it won't hurt the HU) to use a pull-up resistor. This is a relative high-ohm resistor you connect between 12V powerline and the mute, if the mute is not switched by the parrot, there will be a 12 volt signal to the mute lead, making sure the HU does not think there is a call in process.

I have a Parrot MK6000 that I'm trying to put into a 2002 Passat W8 and I am having the exact same issue! The Mute seems to keep the radio in 'Phone' mode even though the Parrot is 'off' (It shuts down like it's supposed to).

Thanks!

Hey hyperplus, take a look at the link below, it should help with the wiring. Posst up if you have any questions after.

YESindeed

ok i didnt read all that was posted cuz i got lazy but this is what i would do.

tap into the front spakers AFTER the amp. you can go to the kick panels to do this and clip the wires and run the ins and outs up to the parrot and use those as the ins and outs for the parrot. as for the rest of the speakers if you cant find the mute wire you can use one of the rear channels on the parrot to interrupt the ignition power lead at the stereo. so when you recieve a call the stereo will just turn off and the parrot will play through the front speakers. you cannot have the parrot play through the rears as well as the fronts. it would just mess up the whole system.

so just remember the front speakers have to be hooked up after the amp and the rears just serve as cut offs to cut the sound

I have a 1999 Saab 9-3 with the exact same problem posted by hyperplus. It looks like there might be some miscommunication above, so i'll try to clarify:

Both my Saab and hyperplus' Audi have telephone mute input for the head unit (HU). In both cases, this pin at the HU floats around 4.5V when normal audio is playing, and then mutes when something pulls that pin down to ground (0V). The problem seems to be that when the ignition is turned on and the MK6000 is on, it keeps that pin (a yellow wire) from being pulled down (i.e. keeps from muting the HU) unless a call is in progress , yet when the ignition is turned off, the MK6000 lets that pin pull down to ground.

I am guessing that in most cars, this does nothing because with the power off, the HU can't come on even. But in my car, the HU is wired to be able to come on if the Tel Mute pin is pulled to ground - even with the ignition off! The idea is that a phone call could be in progress even when you're sitting in a parking lot or whatever and don't want the engine running. So the desired behavior of the MK6000 is to ONLY pull the yellow Tel Mute wire low when a call is in progress (or bluetooth audio is goin on) regardless of the ignition state (on or off).

For the record, I use to have a Sony-Ericsson bluetooth kit that worked properly. Somehow, the HU would stay on during a phone call after the ignition had gone off, but only until you opened the door! doing that caused the dome light to come on and the HU to go off completely. Perhaps that's a clue to how to get this to work.

An additional solution I can think of for those in this situation is to put in a relay for the tell mute signal. hook the coil of the relay up to the ignition wire and ground so that ONLY when the igition is on, the relay is active. then, put the yellow wire through the relay so it can only pull the signal low to ground when the ignition is on. This way, once the igintion is off, there's now way it can pull the mute pin on the HU low since the relay will be off!

I'll call parrot tech support tomorrow and see if they have any insight. I'll post what I find!

Anyone else have any clues?
