i have an alpine cdm-9821 head unit and recently i blew a fuse and lost my radio. upon replacing the fuse everything was working back to normal except i have xm radio set up to the auxilliary setting but the auxiliary setting is not coming up on the head unit now. i figured that the head unit might have to be reset but i don't know how any help would be appreciated. thanks

You have to turn the aux in feature on

1 Press and hold the F/SETUP button for at least 3 seconds.

2 Press the >Fast rewind or Fast Forward> button to select the AUX mode.

3 Press the BAND button to toggle the mode between AUX ON and AUX OFF.

4 Press the F/SETUP button to return to normal mode.

5 To adjust the volume, etc., first press the SOURCE/POWER button and select the AUX mode, then make the necessary adjustment.

For the owners manual for your deck try looking here.
