Just screwed up the radio ... thoughts?

[squeasel]

NEW INFORMATION: update at 1300 Pacific Time. Stereo sound works and so do the steering wheel controls. It seems that there is something wrong at the radio connection (white). All else runs through the CD and works fine.

Can I use a multimeter probe to test the connector and, if so, what test(s) should I be doing?

Attempting to install a bluetooth/aux box to the stereo.

I have the Business CD unit (radio with "computer") and a single CD player on top (no changer). Model Year is 2003 and the stereo is original.

I removed the radio and disconnected the white plug on the side. I then removed the CD player and disconnected a large block connector and a smaller round connector (I will guess for the antenna).

I removed the glove box to gain access for extra wire installation.

Installed bluetooth/aux unit which consists of an addition/extension of the block connector wiring with a split to the bluetooth/aux box and reinstalled all else though the glove box is still loose.

The CD player seems to have power but the radio does not. I removed the bluetooth/aux wiring with no change in status (i.e. CD has power the radio does not).

Have I done something obviously wrong ... perhaps removing the white plug to the radio was dumb?

Any thoughts/advice appreciated.
