If you can live without radio, then the overall look of this _thing_ this struck me as "in keeping" with the look of our interiors and may look interesting on a Sammio dash!

It looks as though you'd still need an amp, but for the price..... well!

Or a square one

i've REALLY got to stop looking at DealExtreme!

Some options for possibly hiding on the gearbox tunnel?

I built in large "door" pockets in mine and put a similar amp in there.

There is loads of room in the sides to put something like this behind a little trap door...

They look great - modern yet retro at the same time.
