Anyone have subs/amp in a 06/07 w/ NAVI?

Accord V6EX-L NAVI 2007
I have 3 10s and a amp w/ cap in the trunk. Has anyone heard of the NAVI DVD getting scratched from the subs hitting(for lack of a better word) too hard? I have 2 fine scratchs around the out side edge of the NAVI dvd. Now the NAVI fails to load some times. It gives me the message "DISC READ ERROR SEE YOUR DEALER." I have had bigger systems in cars with older CD changers and had no problems with CD changers scratching discs. I am going to try to get the scratchs out of the DVD so i dont have to spend $200 on a new one. Was wondering if anyone has had the issue.
 
Thanks

Man that sounds like a pain is the rear!  I haven't heard of anything like that happening so I guess that means that u are hitting pretty hard with ur setup!  I will ask around the shops I know and see if they have heard anything like that happening....
