RCD-510 into a 2008 Passat Wagon TDi with stock radio/single CD

[jackafrica]

Hi,
After using the search function I've managed to work out that I'm confused! Happens easily to me in these circumstances of electrickery.

Currently the car is fitted with the stock RD500 radio/ CD. The MFD is the red one.

Seeking advice on fitting a RCD-510 and a 9W2 Bluetooth kit into a 2008 TDi Passat wagon.
I've already bought both of these pieces separately, over time.
The RCD-510 (with USB output port on the back of the unit) is ex China, the 9W2 from Sydney, but probably via China too.
Have I painted myself into a corner?

My main desire is to be able to play music from an iPhone4S as well as the Bluetooth phone basic functions.
Of course the bonus of 6 CD changer is also there for me.

I would prefer to have an outlet, somewhere within reach for a USB outlet and or a 3.5mm plug.
Can't seem to find where such an outlet would fit in the 2008 Passat.
On ebay there are these for sale, but where do they fit?



Of course, if there is someone (or a business) in Hobart who can offer to instal the items in the car and do the coding or whatever is required, I'd be most grateful for the information.
Would prefer to fit the unit myself if I can. Have seen the YouTube video on removal and replacement.

Is there any issue to be careful of when asking whoever installs the two pieces to be sure it all works.
I know an auto electrician who has offered to do the installation, but he doesn't have any coding equipment or the VCDS or VagCom.

Thanks for your patience.

Cheers,
Richard
