Yup, only one level of brightness on the Modulus, lights on or off.

There are some nice features it has though... It does support RDS data and the Auto FM tuning is great on roadtrips.

It also seems to remember the bass and treble settings for each CD and radio station I'm using, either that or it is defaulting to 0-0 each time. I haven't really played with it fully and I haven't totally digested the manual.

I'm not sure but I think it has adaptive volume too, could just be my imagination.
