Blower speed, whether set manually or left on Auto, doesn't directly affect temperature of the air coming from the a/c.
It could be also a poor electrical connection with some of the sensors. It's not only the one on the dash, but also inlet temp. sensor, sensor on the evaporator, and two output temperature sensors (on the vents and to the footwell).

I don't believe that CD player has any affect here - they all get quite hot when switched on. The dashboard also gets very hot when you leave the car on the summer sun, but this doesn't affect temperature control either. Sensor isn't in thermal contact with the dashboard (except via its 2 wires). But it is possible that you disturbed some wiring when you mounted the player.
As Stempy said, try cooling (or warming) the sensor and see if the regulation reacts. You should hear mixing flap motor spinning (at least on mine I can hear it) within 10 s or so.
Ask in local Citroen garage if there is some diagnostic device for this. Tracing the problem would be much easier that way.
