Navionics Issue with Hummingbird 385CI

[sapper3]

I purchased the Navionics Hot Map C Premuim for use with my Hummingbird 385CI. I have inserted the SD card in fish finder, Check that Chart setting was on Auto. And It does not come u? Now the boat is not in the water so not sure if that is an issue. Can any one help me. I am heading to Lac St Anne tomorrow and would like to try it out before I head to old Lake on Weds. Thanks

Most updates you just save on to an SD card from the mfg website. Install the card in your unit and it shoud upload automatically.
