Added this solution today and I am really pleased with it.

Griffin make a charger for the IPhone, the AutoPilot

So, what makes it so special in this case:

1. The head is really compact so you can simply insert in the batwing cig lighter socket without sweating that it will be crushed at full lock, there is still a small clearance

2. There is a seperate 3.5mm take off in the head of the device, so you can feed that in to the Aux of the HK headset and you are fully connected. This means you only run the single IPhone connector to the IPhone and that takes care of charging and bring the sound back

3. There are buttons (basic I agree but better than nothing) for play / Pause, forward "wind" and "rewind". These are big and can be operated with a glove on

I have my Iphone in a ram mount and only a single lead going to the Iphone

Very neat

 

Any pic of the set up?

 

WOW great find, thanks for the information

 

Not sure pic will help much but this is about all you see of the wiring

It is a very compact device

 

Still have to mount the device somewhere...

 

Thanks for the info.

 

As stated in the OP, I use a Ram Mount in the bars which I am happy with. Very common solution to that problem, but not really what the post was about.

This device allows you to run a single cable to the IPhone and connect to the Aux in the stereo and charge. Much neater

 

Finished up the install today. I know you can pull the AUX connection through the back of the headset and that would be neater but I am reluctant to pull the headset apart so I opted for the face entry.

I ran the cable in the gap under the headset

I had to modify the 3.5mm jack cable connector at the charge side as it is a bit tight in that corner of the fairing. I trimmed back the plastic support and created a compact 90 degree bend. Very pleased with the results and the basic control of the ipod functionality is very easy with gloves on

 

That's the pics I wanted to see. Nice job!

 

I have the new Boom Audio Magnetic tank mout bag for the Iphone/Ipod,I think it would work well with this setup too.
