Is it posible to add a2dp support to non-a2dp bluetooth car kit

I've got a "Nokia CK200 car kit(Car kit)":http://www.amazon.co.uk/Nokia-CK-200-Car-Includes-Cable/dp/B003I77BC2 that I use for making and receiving phone calls hands-free. I've successfully integrated it to my car audio system. The connection to phone is via bluetooth. Although it's a great product, it lacks a2dp support which prevents me from streaming my music in iPhone wirelessly(iPhone supports a2dp streaming only). So I thought that could be another quest to add a2dp support to my existing, non-a2dp bluetooth module. Now, my question is, if I get a bluetooth module that is a2dp enabled- this could be anything from a headset to a2dp receiver (they're cheap and available almost everywhere), can I take its "a2dp support" and add it to my car kit bluetooth module. Sorry again, if the question is stupid.

Hi

I found a video on youtube that make it possible to add a bluetooth module to an existing none a2dp bt. You can check it out: https://www.youtube.com/watch?v=slMZ2EDR5Ko

Maybe you can find the cheap BT in your electronic shops.

Cheers.
