i have followed the instructions to make the disc but it wont let me go to the navi menu it keeps saying insert appropiate disk if anyone could help that would be great

thanks

Are you in the "Background" menu, or are you trying the "Read from disc" menu button?

Did you just get this unit. Have you installed the east/west navigation disk yet. You will need to insert one of them first to get the nav menu working. Once installed you can pull the disk out and then you can go to the nav menu and insert your disk with pics. If you don't have the navigation disk set just check around here on the forums there are ways to download them and make them yourself, or you can purchase sets pretty cheap on ebay.
