Quinte Fishing

Just purchased this 2004 unit used. The navionic 2005 Gold chip will not show all contour lines and depths. The chip works perfect in my Lowrance LCX-27c. Any tips to make it work right.

First thing to try is a software update on the unit. You can do that here http://www.humminbird.com/Support/MyHumminbird/

After that if it still isn't working you can try to do a Restore Defaults on the unit to bring it back to factory settings. This is usually located in the system portion of the menu.
