Navigation DVD player issue

[tcn2k]

I need to bring my car in but wanted to check with you all. My navigation DVD player would now keep asking me to insert the navigation DVD. It seems to be bad. It does it when I turn the car on or in the middle of driving, my nav screen would go out. I have the "Map my direction" on the small screen. It was working just fine until this past week where it kept saying it can't read the dvd. I took the dvd out and cleaned it and yet the issue continues. Anyone have the same issue? Is it a bad DVD player? My car is only 5 months old. The DVD seems to be in perfect condition.
