Thread: Micro SD Card for Helix 5 G2 GPS

I recently purchased a Helix 5 Chirp G2 with GPS and am putting in on my boat. I also found a use Navionics Platinum + card for Central and South Florida. I haven't has a chance yet to use either one as I am waiting for a few items before completing installation and getting on the water. The Chip is still in the mail also. My question for those in the know is when I have the Navionics card in my unit can I put WP on the card or do they go to the internal memory of the unit? If they go to the card do I need to worry about overloading the card over time as I increase the data size being stored? I will also want to store routes and perhaps contours to keep from hitting things. This will all take up memory. Or do I need to put in a blank Chip and use that to record this stuff so that I don't pollute the Navionics cards data. last question If I store things on the Nav Card can I restore it to the factory setting or should I make a backup somehow?
These are just my thoughts from having never used on of these before. Thanks for any clarification or guidance you can provide me.

Thanks for educating me. I just got it mounted and will be playing with it in a day or two after letting things setup. My chip should be here any day. Early Christmas.
