Has anybody taken apart a PnP unit to fit in their car (or I suppose home - though unlikely)? I'd be interested to see how connections were made as well as any excess case material relative to the logic board. I'd prefer one of the smaller rectangular units, but otherwise it doesn't matter. For example, is it possible to use any of the units without a dock? I assume one would have to splice some wires and solder, but otherwise it would work.
