Replacing Bose stereo with Pioneer Double Din Nav?

[andythilo]

Hi

I really want an integrated Nav solution for my new 6 Sport (UK). The Stereo can be replaced with a double din unit I know, but its Bose. Can I use the preouts into the Bose Amp or will I have to bypass the amp completely and wire the factory speakers upto the Pioneer?

Also does removing the stock Bose have any effect on other car functions, i.e Heating/Ventilation controls etc.. or is the new stereo just that,just a stereo. I had an old 6 where the whole lot was integrated and a pain in the ass to change out.

Mazda sell the steering adaptor so that I can keep using the volume controls etc.. apparantly. Does anyone have any knowledge on this matter?

The nav unit I want is this one :

Mazda sell the wiring harness for it but it's for the non-bose system. How hard is it to run the speaker wires from the bose amp output back up to the stereo? I dont really want to cut anything if possible so I can go back to standard if neccesary.

Thanks for your help in advance.
