I was sent a new chip, and all is well. My chip was faulty.

I got some help from a higher-up from Lowrance this evening. He showed me screen caps of v14, v15, and v16. All of them have the data I need for my lakes. After describing all I’ve done to try to get any data to show up from the card, they are sending me a replacement. Great customer service!

I don’t have anything for “Map Details.” I can pick “Lowrance” or “Navionics” for source, and I can decide what info overlays I want. I don’t see any “Map Details” option anywhere on any of the menus.

That is actually the detail I am looking for; that’s my buddy’s v14 with all the roadbeds, etc.

This is what shows up with my v15 map card in… or out. Doesn’t matter.

Does anyone have v15, and the name/location of a lake that has a bunch of good stuff from the card? I can go to the lake and confirm against a known lake that my card is not in fact working when compared to another card of the same version…

I actually did that last night, but did the hard reset versus the soft reset (pressed the +/- buttons rather than the Pages button). Not worried about losing data, I’ve only had it a couple weeks anyways. Getting the data to show up (submerged railroad and road beds, etc) is 100x more valuable to me for these places than any waypoints I could save.

No.. I have Lake Insight v15. With no card in it at all, I still see the dropdown with Lowrance and Navionics.

I wish I had a Navionics map card at this point, haha!

Nope. No matter which one I select, it only displays the base map of the unit.

The unit is running software version 4.0.5.1.13, by the way.

Yes, I did that. I have two options: Lowrance and Navionics. Of course, I picked Lowrance.

I downloaded Insight Genesis maps to another SD card, and was able to view them. Just nothing on my v15 chip.
