Hello, I have a 2003 525i that I lugged over to Hawaii and the Navtech disk will not work. I had the 2002-1 North America disk but it doesn't work here. I just bought the 2002-1 Northwest & Southwest disk off off Amazon. It said it works for Hawaii but it doesn't. Navtech discontinued making disks or having any info on which one I need. I live on Oahu specifically. Anybody know of a hawaii disk?
