Lowrance local maps

[Dramad1]

I'm looking for some local inland lake maps for so cal to load on my lowrance unit.
I know you can buy preloaded maps but was unsure where to buy. Are there a any places around sd that sell the preloaded micro sd cards? Maybe dicks sg? Possible tackle shops?
I was also wondering if there is a section in this forum where members share maps, waypoints etc

My Lowrance unit uses a micro sd card from Garmin Navionics and I just uploaded west coast maps from their website. It includes lakes. I had to do it twice before it worked in my unit, not sure why?

This is what I bought for my Raymarine, although I didn't know Garmin owns Navionics now;

There is also this if you're interested in a more in depth layout of lakes

So question^? Do you buy the digital copy and then have to download it on your own sd card or do they send you the maps loaded on a sdcard

I downloaded it so I can have a copy and then transferred it to an SD card. I wanted a larger sd so I could save more info on it

You can buy last years maps on EBay. They come as a chip, you just plug it in on mine.
