I have an 04 honda accord coupe ex-l 4cyl. My navigation system stop working it was working fine till about a week ago it just stopped out of nowhere. I took the cd out and check for scratches nothing. I put in back in, it shows on the screen which is a green background that it's downloading the maps. Like 2 seconds later in says please check your cd. I even order the new cd from HERE the Hondas map provider and tried it same thing happen. Please please help me. If there's a cheaper way of going about this. Because the dealer told me and quote me that it may be the system and to fix is like 300$
