navionics us644xl?
 

I purchased this chart chip on eBay assuming it would fit my unit. Turns out it doesn't. Does anyone have any knowledge about this chart chip and would anyone have any use for it? It covers Southern California and baja

Can you transfer the info to a SD card and then use it?

I don't even know what kind of slot this chip fits in. It's weird. I'll take a pic

Contact Navionics, I'm sure they'll tell you What unit it was made for.

It looks pretty similar to a navionics chip that I had installed on a Raymarine C70 unit back when I had just boat. I think those are called MMC cards or something like that.

After surfing the net a bit I think this is for older furuno units. Gonna put it back on eBay. Maybe I can recoupe a couple bucks

Looks like a CF card. You might be able to take a multi card reader apart and plug it into the CF slot. The top looks like they added it to keep the general population from copying the files.

This is way bigger than a CF card.

True

11year old charts?

It was 20 bucks. I just grabbed it on a whim. Wanted to see if it added any layers to my stock chart

Wondering if you still have nav chip
 

Hi,
I'm a NCKA member and saw your post on this site. Do you still have the nav chip? I have a super old gps and I think it may work for me.
