PonyRider, that device would be handy for keeping the laptop charged on the run. As my phone has wireless charging capabilities, concealing a charging pad somewhere is also on the cards. cj429, that is an interesting idea. Back in the day the radio sound was mono rather than stereo. Sedans and coupes had an optional rear speaker with a fader control located near the lighter, looking a little out of place. I like your idea. The cigarette lighter location would be perfect if I decide to use it. Original units are hard to find. I obtained one ages ago.
