HomeFeaturesAdvanced How-to – Updating Navionics Chips There are things that anglers need to do to in order to get ready for the fishing season. Organizing tackle and cleaning rods are done, but one of the most important things is tuning up the electronics, and mapping is one of those items. A lot of anglers look at mapping as vital, and Navionics offers anglers the chance to purchase an update chip for $99 and get the latest data and even choose the region while updating one of your current Navionics chips. Our managing editor, Dan O’Sullivan recently went through the process in updating his maps from his Northern California area to Alabama and some of the nearby states. He filmed the process – complete with forgetting to set the area – and being able to go back and start over again. If you are a competitive angler, and need the most current information available; this is a more affordable way to get new maps without buying new chips.
