NAC: how to install an input jack on an OEM radio?

In the "old days" that might have been easy - just find a preamp level 
signal, tap in, add a switch and some input jacks.  These days I suspect 
it would be tougher to find the right place to inject the signal - for 
instance, volume controls, which are a great place to "cut in", aren't 
nice little pots you can solder into these days, they are solid state 
devices.  As is the selector switching between sources.

My Nakamichi has an "aux" input, although I didn't bother to plug in the 
jacks and set it up when I installed it.  But it's not "OEM"... I think 
the best solutions were pointed out here - find an FM interface that 
works well with your rig, or one that taps into the CD changer wiring.
