Thanks David, yeah, I found that link as well and is a great source for 12v.
That said, as I think more about it (dangerous),I'd really like to cook something up that would use the GPS mount which I will never use and is in the way of my current clamp-on phone mount.
There's a nice snap on cover over the GPS pinouts which I believe I could mount my phone to using neodymium magnets (I already do this in my vehicles and it works great).
If I could find a good diagram of the pinouts that's not in German, and possibly the female connector that would fit inside the cover, that would be sweet. I'm thinking I could modify the cover and add a very short mini USB which would be wired to the correct pinouts and have a very useable set-up.
Here's a shot of the pins I am referring to (pic borrowed from google)
I'll be away from my computer for the rest of the week but will be checking back in as soon as I can in case someone comes up with some suggestions.
