I'm planning a fly-drive from LA - Monument Valley - Grand Canyon - Vegas - San Francisco as the first part of a honeymoon next August-September.
It's been 10 years since my last visit and with the change in technology since then, I'm thinking about using Sat Nav (alongside atlas) and we'll probably both be bringing mobiles.
My first question therefore is whether it's worth buying the US maps for my Tom Tom One or hirer one when we get there. Only thoughts of bringing my own is that on a recent trip to Monaco, we hired a Hertz Neverlost and it didn't pick up signal once and obviously I'm confident with the workings of my Tom Tom.
Second question, probably a bit dumb, but do the cigarette lighters in US cars work off the same voltage as UK ones. Just thinking we'll need to use it for charging the Tom Tom and our HTC mobiles.
