Navionics Hot Maps

Questions / opinions. I got the cabelas gift card ,christmas,went to bass pro,got the navionics east chip.i called humminbird prior to purchase.they said upload new software onto the 998 c hd di/si and the 798 ci hd di si before uploading the navionics.i purchased as a leg up for new resevoirs in Tn.the chip has the drawdown capability for depth offset etc. .my biggest questions are 1) split screen in a side find mode looks fairly simple.??? Dont want to waste a lot of time initially learning the capabilities when i could be fishing.2)talking to the guys on Tn Anglers , the overall preference for fishing ,not navigation,the most thumbs up seem to lean towards the navionics..aparently i need to purchase a 32 kb max sd card to upload updates from humminbird,the tech said to large of a card could cause issues.opinions,advice???

Get a class 10 32GB SD card on Amazon. (they're cheap)

Okydoky Chuck....when are you coming down.?

Okydoky Chuck....when are you coming down.? Should i get 2,guessing different upload/ updates software for 2 different units didnt ask...duhh,or just upload one install it,erase it( no clue how to do that either) and then upload the other...or maybe the new software will work on both...havent upgraded in 2 years,no need,i knew where i was going.

You need an adapter to plug the card into a USB slot on your computer, but once you have it the card shows up on your computer like any other drive that you can explore making it easy to delete/replace one update with a later one. I wouldn't expect Humminbird to release another update for these older models.

Check out youtube for videos on how to operate those units. Doug Vahrenberg's channel is fantastic.

Keith, check your laptop - it may have a slot for an SD card already. It can't hurt to get two SD cards. If you look on Amazon there are all kinds of deals for them, like buy 2 for $15, or get one with a card reader, etc...

Are you in TN already? If so, I think they give you a special depth finder when you get there! You take off one shoe, hold your nose shut, and then step in the water!

Not there yet.august 10,plane to nashville. I found a card reader,the kid left it here.

The platinum chip came yesterday,unfortunately the sonars are packed.it did come with a usb port card reader for online upgrades to the chip,free for 1 year,not bad.
