I have a e66 730ld 2006 with tv and sat nav. I dont have a cd changer. They are usually situated above glove box. I seen a few cd changers on ebay.
Can anyone advise me in what i need and whats involved to install a cd changer in the boot next to the satnav player already in boot.

Is the wiring already there in boot or will new be needed goin to idrive in front etc. Is it worth doing, what do you think?

Which model if changer do i need?

Thanks in advance for advice.
