I too had to replace just about all the bulbs for the climate control!!
I found if you gently lever the hazard light switch off, you can use that hole to get your fingers behind the vents to pop them out.
As for the band expander, I heard if you only plus into one of the wires, you will loose conversion, therefore signal, in low signal areas, as the unit goes to the thinner wire aerial - I think it is called FM Diversity.
I too find the reception is pretty crap, and are thinking of fitting a 'normal' aerial somewhere rather than the glass one --- anybody got any ideas of what type and where to mount a normal aerial????????
