Ooh, glad to hear that! I'll need to search around a little harder and see if I can learn from their experiences.
Sounds like Slammd wants to make it so there is a dash-mounted USB receptacle that is water proof and is a direct connection to the head unit, this will allow him/her to mount iPhone on bars and plug into that to allow track/playlist/etc skipping from the left grip controls.
This will pass digital audio to the head unit and allow for charging. All audio should come through the stock speakers, including GPS instructions.
The problem I am seeing is that the voltage drop from the long cable may not play well with the iPhone. Newer models just won't recognize anything below 5V.
I didn't check the specs, but I'm assuming that Honda fully supports Made for iPod (MFI) specs which will allow the iPhone to connect with it. All other receivers I've used that have MFI will connect to my iPhone 6+.
The other link I posted for the Honda USB head unit connector is from China and will take a month to get here, I ordered one of these after I realized my 1 month mistake.

If it won't connect due to voltage drop I will use a glovebox mounted 12V>USB device to power it and pass the 2 data signals along on that after soldering the data wires from the head unit to it.
Yeah, it does sound like a lot of work, but it will be nice to be able to clip my phone into the cradle, plug in the Lightning connector and have full integration.
I never listened to music much in the past while riding, must admit I've taken a liking to it!
If it works I'll post the steps I took, with pictures where necessary.
A Bluetooth solution that integrated with stock controls would be great, but without integration it is too much of a distraction to change tracks. Also charging will be nice, esp if using GPS.
