Crappiegirl check your unit and write down the software version number then check humminbird website and verify they are the same. If not redownload on a formatted sd card and try again. I have 2 997's and they have been easy to update and run my buddy has a 898 if need be pm me and ill try and help u figure it out. Check the "faq's" on humminbird also for similiar issues from others.Hope this helps
