Hi

Can anyone point me towards an online specs chart/matrix that I could
use to select a solid but essentially basic head unit that plays 'real'
and MP3 CD media, and also has a rear line input that I can select from
the front panel?

RDS that overrides the line-in and any other currently selected input
would be useful too.

I don't plan to use amps, external CD changers, etc.  I have a historic
preference for Kenwood and Sony, so something listing at least these
sets would be great.

TIA
