i know this is for the TL section but can someone help me out with this...my brother has and 05 accord and the nav keeps reading please check disc. does it need it's own disc? plus it wont load the to the main screen where it says Honda Nav..it just goes to disc error etc etc.

 

take the disc out and clean it with dawn or something like that. Dry it then retry it. If that doesnt work.... Well you have bigger fish to fry....
