Hi, I am looking for the update disks for my npd5500 navigation system. I have tried contacting vdodayon which is the company that supplies the disks that runs the system. They say the don't make them anymore. The disks I have are 2003 disk and am looking for something more up to date. They said I could buy a new disks set but they could not tell me which one would work in my system. If anyone could help me it would be appreciated. Thank you.
