might look at the powerlink jobby, have a couple of devices that charge via usb, phone etc. Use co pilot on phone as Sat Nav, (esp since it dosnt use internet on the phone to do so). have to figure out a way to combine the powerlink set up into the 3CS solution.
going to have a 12v, and usb charge point on aux shelf on handlebars then hook a pd oiler into rear light wiring. will leave me a spare connection on 3CS for aux lights in the future.
