Thread: HB 788c and 797si ?'s

My question - I know I need a memory card for each to save waypoints, etc... I think they will both take 2 - do I really need 2 for each, or would I be okay with 1 in each - and what should I get - thinking just a basic SD card from Best Buy or something like that...???

Thanks in advance...

You don't need memory card to save waypoints. They are save in internal memory.

Those SD slots are for addin on upgrades and maps by Navionics

I have the exact same set-up on my boat, you will like it. If you don't have the maps already on the unit itself, one of your spaces will probably be taken up by a lake map. My 797 only has 1 slot, I just remove the card when I want to update the unit.

SEMOMike... so, I'm good without, but if I want to add anything to them, I'll need cards... These maps - do you get them online, or is it something you buy? I'm assuming you buy them : )

Cabela's -- Lake Map Software

click on above site at Cabelas to see what map cards there are that fit your unit. Its great to buy last years card at sale prices as must lakes are only updated every few to 8 years, except of course for the new hi deft lakes on biggie dollar cards. You have to read what works in your unit plus of course see which have your lakes on them. When you buy a blank SDHC card to save as back up all your sites stay with the Sandisk brand as they always work in HB stuff without fail.

depends if they are already preloaded in your unit. If you turn on the finder, and go to the gps "section" are lakes with details preloaded. If not you have to buy maps, used to be about $100 a piece, but you might be able to find the
navionics cards cheaper now

You can use the memory card to capture images from your si, put the images on your computer and you will be amazed at the details you can see on the larger screen. Jody@Hummingbird taught me this.

When you buy your card, you might want to investigate what kind of card slots you have in your pc..

Although SDHC card readers are very cheap, I wanted to use the card reader already installed in my desktop pc...

My desktop card reader being an '07 model only accepted SD cards... big difference....an SD card reader will not read an SDHC card....

I bought the Sandisk Extreme III 2.0 GB SD card...the largest Sandisk makes in the SD format....
