It has apparently been updated to the latest 29 firmware. Will this unit run any and all Australian MAP CDs/DVD's? BMW Sydney inform me that MKIV has never been sold in Australia, sould I stick with the MKIII?
I am told by BMW Sydney that my car is partially wired for NAV already (they say all Aust X% ever built are) and that I do not need to rn a loom but rather I need to purchase from them a smaller loom kit ro add to the pre-existing loom.
I am intending to fit the NAV system myself, any help that anyone has in providing more info would be great, thanks.

Contrary to the previous post, you have 90% of what you need for nav.
To add nav you need
1. GPS antenna
2. Navigation computer + mounting brackets
3. Wiring loom to plug nav computer into TV tuner
TV tuner is mounted in the spare wheel well, nav goes on the LHS of the boot, just in front of the tailight, under the window
You may need to change the trim panel - compare your car to one with nav.
And the GPS antenna mounts inside the spoiler on the tailgate - fitting the GPS antenna will be the hardest part - unless you are lucky and already have the antenna fitted...??
You may also need another loom that connects to the light control module (LCM) and instrument cluster (IKE) to deliver the wheel speed pulses and the reverse signal. There's a cheat way around this to remove the hassle of running cables the length of the vehicle: connect to reverse light, and radio TAA tacho signal - both available in the boot already.
Or this loom may already be fitted..?
Anyway, start by downloading and reading the retrofit instructions - available on this website somewhere - they show you the wiring required, most of which you already have.
