I am having an issue with my new 858. The unit powered up and i was able to cycle through all of the screens fine, then I powered down the unit and put in the new Lakemaster card. Powered the unit back on and now the only screens that I am able to view are the depthfinder screens and NO navagation screens. This unit is also connected to a new ipilot link trolling motor.
Has anybody has this issue? I have contacted humminbird to see what they say.
