Hi Mate,
Here's my setup. I will be installing a 7" all-in-one double din unit. What I currently have is the stock head-unit with the honda ipod adapter. I plan to keep all these so this is what I'm doing.
[Factory Cable]

|___[To factory headunit]

\__[To new headunit]
I bought the following:
- 1 x Honda Double DIN Fascia kit
- 2 x Female Harness
- 2 x Male Harness
- 1 x 7" All-In-One Unit (awaiting arrival)
The above will allow me to retain the standard steering wheel controls with the above connections, connect the aftermarket stereo to the OEM speakers. I needed to order a pair of each harness because the harness you get from ebay is missing some pins, check EuroSteve's previous post.
If you are going to connect your new headunit to an amp then you will not need the speaker cables, you can then recycle those pins/cables for the steering wheel control.
Hope that helped?
