Audio Systems: Bluetooth audio, mazda 3s, hce 16

Question
I am looking to buy this: http://www.allmobileaccessories.co.uk/buy/sony-ericsson-hcb-700.shtml  with this accessory: http://www.allmobileaccessories.co.uk/buy/product_sonyericsson_hce-16.shtml

Is it at ALL possible to install it into a Mazda 3S 2006 model? A few people told me that it is nearly impossible to install and line a bluetooth car kit into a stock audio system. What accessories would I have to buy? What would I need to do? Is it possible?

Thanks,
Harrison

Answer
First of all:
Anything is possible with enough money. To wit: I had a 286 CPU running my mobile audio and security system in 1990.

It may be 'nearly' impossible, but that still leaves it open to being done.

I cannot help you beyond that fact, since I deal in standard mobile audio technologies, of which Bluetooth is not yet a part of.
