OK now I'm facing old age and a general state of confusion, I thought now might be a good time to look at some in-car route finding assistance. :?
I can read a map...it would be embarrassing if I couldn't, I spent over 30 years drawing them. However the prospect of driving in Europe without a navigator, (occasionally) I thought I'd invest in a "Tom Tom" or some other gizmo.
Most run off a rechargeable internal battery but from what I can see they don't run for long between recharges (just a few hours in some cases). There is of course a lead you can plug into your ciggie lighter but my '58 Ghia is 6 volt.
So the question is, what's the best way around this?
