Nissan Repair: warning lights, nissan altima, warning lights

Question
what is the meaning of 3.0 h. It was flashing on my monitor screen in nissan altima 08.

Answer
John,

The only thing that I know of that lists 3.0 is the CD loading control.  The h indicates heating?  I would check the DVD Nav book for a listing.  Sorry I could not have been more helpful.  Please email me back and let the group know what you find.
