Adding A2DP Bluetooth Receiver to Nokia CK-200 Car Kit for Wireless Music Streaming

I've got a [Nokia CK 200 car kit][1] that I use for making and receiving phone calls. I've easily integrated it to my car stereo system. Unfortunately its lacks a2dp profile which prevents me from streaming music in my iphone wirelessly. The manufacturer states that the reason for not adding a2dp is the kit doesn't output stereo. After searching for ways to alter the unit to output stereo and add a2dp profile to the bluetoth and no success I thought I could possibly buy a [bluetooth receiver that supports a2dp][2] and somehow integrate it with the kit I got. Now, here's the kit itself:

[![Car kit wires and stuff][3]][3]

What I need to perform is the following:

1. Wire connections from bluetooth receiver to the speakers
2. Feed the receiver when ignition is on so that I don't need to recharge it externally.
3. Send mute signal via the vacant mute wires whenever music is being streamed.
4. A bonus would be to make sure that once paired bluetooth device is not forgotten so that it connects to the device whenever the ignition is on.

Do you have any ideas how/if it's possible. Thanks in advance.


**EDIT**
Just to make one thing sure: I don't mean to be able use both hands-free kit and the additional bluetooth receiver. Just being able to use the bluetooth receiver is OK. I just want to use this cable harness to avoid any damage to the car wiring. That junction box is probably redundant in the design I wish to achieve.

Please check previous forum question you sent:

İəve seen that video already. That head unit has got AUX input. But mine doesn't. If I had AUX input that I wouldn't even bother with bluetooth stuff.

You said in your previous post you have already integrated the nokia car kit to your car audio system. I'm curious on how you connected them. Anyhow, you are correct when you said that your head unit has no AUX. What is your head unit by the way? If your manufacturer states that it doesn't output stereo, I guess that would be a trouble. What inputs that it allow? cd? tape?

Connecting the car kit is pretty straight forward. You just connect the cables coming from car to the car kit harness and the other end of the harness to the tape deck. Everything is controlled by the Car kit system. My head unit is Becker 3100 and it's a very good one. It outputs stereo. It has Dolby system. It allows both tape and CD. Here's the link to its service manual.

Hi,
From the model you showed here, I believe it would be hard enough to integrated the A2dp Support you are looking for if you don't have additional AUX. I don't know if this would be of help, maybe you need to add the aux capability just like in this video? https://www.youtube.com/watch?v=wwuTP8FwNXM.

Cheers,

I had same problem with my Sondbot Kit before . I didnt find any solution so I changed it with  Nulaxy KM24 Bluetooth Hands-Free Car Kit . I have had this about one week and it is really a nice product with some room for improvement which might only be a firmware update if that was available. All of my experience was using Bluetooth since that is the main reason I bought it. I chose this model over the others because it was the newest and was hoping Bluetooth issue was resolved in the latest version.The audio quality when playing music is very good. With very little to no noise/fuzz unless volume is very low and even then it is rare.It pairs with my phone within a few seconds of being turned on and I can play music on the phone or stream it.The controls on the device work well for me when using music on iPhone 6 or amazon music work to skip forward and back.The positioning neck works pretty well keeping the device where you want it and the display is easy to read although you rarely need to see it unless using another music source like USB
