Aquaman,
You’re confusing me here (which is getting easier and easier to do!):
In your first post you stated that “The unit has an enternal gps”. Now you are staing that it “has Internal gps i dont have a puck with it”. The “I” in the model number means that it has an internal GPS but by your statement in your first message I assumed (uh, oh…) that you had purchased an external GPS Receiver. If the problem is with the internal GPS Receiver than there is not much point in trying to test it with an external GPS Receiver. Whatever the problem is, it is contained in the unit so you need to call the Humminbird Customer Resource folks at 1-800-633-1468 and get your unit tested and fixed.
