Hey if anyone's still following this thread I worked on it some more today - and got nowhere!
First of all, to clear up what djh3 said about a connector up front by the neck, no such luck on a 2010...that is either for later years or only touring models, or both.
So to see if the problem is in my extension cable I opened my fairing and plugged the ipod adapter from my saddlebag (pictured above) directly into the radio harness inside the front fairing - then plugged in my iphone and at first I thought there was NO TICKING but my excitement was short lived when I realized it still wasn't charging, and before I was done dicking around with it the ticking was back too.
Something is very glitchy about the whole deal and now I'm starting to suspect the N-Touch 30pin adapter - or the radio head unit itself. Looking for a pinout diagram
to better understand what's happening with all those wires on that 30-pin adapter if anyone knows where to find one. Also wondering what's inside that black box - I figured it was just some noise suppression resistors but maybe there's circuitry that's been damaged?
I mentioned in a different thread that my adapter had been mangled by its former owner and I repaired it (Pic below). I have learned from today's trials that the 2 plugs serve 2 functions - the smaller one with 3 wires is audio only, while the other larger bundle is controls only, one of which should be the charging wire. Another curiosity is if I unplug the control cable the ticking instantly and completely stops, but the music keeps playing, I just can't change tracks.
Here is the way my plug looked before I repaired it:
Here's the repaired cable plugged directly into the radio harness inside front fairing:
