carbon unit is networked with a Gen 3 at the dash and at the bow.
with lake Fork boat lanes chip loaded on the carbon, the gen 3's show only the waypoints etc, not the trails.
shouldn't they all be the same if networked??

This should help. Will work for Gen 3.

Question for all you Lowrance geniuses, of which I am def NOT! Bought a used boat a few months ago that has 2 gen 3 HDS 9's on it. One at the bow, one at the console. I bought a used Gen 3 HDS 12 to add to the console and hired someone to link the three together. He did. Supposedly. I have a new Ultrex up front as a side note and I'm aware it won't link with Lowrance units. I have an LSS2 transducer mounted on the transom and it read both units fine. The 12 is supposedly linked to the console 9, and if I go to source on the 12 it shows the 9 as the source. The issue is that when you go to side image on the 12 the page will come up, but it will not read the transducer. I took it back in and he said it wasn't linking because I didn't have the 12 updated to the newest software. He updated the software and it's still not working. He's now suggesting I update both 9's with the latest software. Any ideas?

Not a genius and I’m guessing here. Go to your 12’s Structure Scan menu (you know, press the menu button while on the SS page). Go down to the source and make sure it’s NOT set to “this unit”.

Thanks Scout, but it's set to the console unit for the source, which is the "brain" for a lack of better explanation. At least that what it says it's set on. Could be the guys set it up wrong, but I don't have any idea how to determine that. Guess I should have stayed in school!

I purchased a used Lowrance HDS9 and it has some co-ordinates left in it. Lots of them. Most are waaaay out of my range of where I'll fish, but some are within 300 miles. How can you put in the co-ordinates and get a location so I'll at least know what lake they are for? Thanks!
