I am having trouble with the DSP settings. ON XM Radio, they do not "stick" after you have set them. For all of the other modalities (regular radio, CD, DVD), the DSP setting stay where they are set. But, with the XM stations, everytime you change, or restart the car, the DSP settings have returned to "Off".
Anyone else having this problem?
I have looked in the manual, but not much help.
