Has anyone had an occasion to add a USB port using the outlet for heated clothes? Is it possible? Is there a better or easier way? How do people power their iDevices for use of their GPS/phone?

yes, there is even a plug-in USB for that port

Actually this is not the SAE (which you would use for heated clothes) but the general powerlet port. Don't use the powerlet for heated clothes or you'll blow it. I know. I did.

See also there is a thread on the "BMW mystery plug" on the front of the bike, which may or may not be wireable into a USB.
