cushieaudio for accord euro

04' Accord Euro Luxury owner

Hi, I'm wanting to purchase a Honda iPhone, USB car kit from cushieaudio ( http://www.cushieaudio.com.au/honda-usb3.html )

But I see they sell about 5 cables seperate to the kit itself so I'm not really sure what I need.

I do know that while the unit is capable of bluetooth I don't want to buy the pieces for that yet as it costs $50 and it will rarely be used.

Pretty much the sole reason I want it right now is for the ability to play songs from my iPhone 4 so I'll definitely need the cable for that.

This is what I'm thinking but would just like some confirmation first;
USB / iPod / Bluetooth Box (U3i-HON1)
Data Cable (HON1M)
USB Extension Cable (6Ft Male to Female)
Pod / iPhone / iPad Custom Cable (5Ft) (The 15ft would be a bit excessive and messy?)

Cheers!
