FM modulators and such

I have a 06 Cad STS with the factory head that has computer interface functions that would seem to make it impractical or perhaps impossible to change with a more capable model. If I'm FOS about that, please say so.

So I suppose that my only real option is to go with an inline FM modulator. I did that back in the late 80's with a multi CD changer and it took about 4 tries to find one that worked acceptably well. I'd like to have an USB jack for thumb drives, bluetooth and 1/8 jack. Or at least two of the three :smiley:

Any suggestions for quality equipment?
