Navionics charting questions - need help with charting?

[Wayne P.]

Recently Purchased Navionics+ for use with a Lowrance Elite 7 HDI unit.

Downloaded map area that includes the Toledo Bend Reservoir on the Texas/La border. I had looked at the online map on Navionics web site and really was impressed with the level of detail shown. Specifically, the boat lanes are a nice feature that was one of the reasons for the purchase. In the sample image below taken from the Navionics web site, you can clearly see the North/South boat lane represented by Green/Red markers on either side, and an auxiliary boat lane marked with Red/White circles.

When the map data I downloaded is displayed on the Elite & HDI, the Green/Red markers for the North/South boat lane are missing. The Red/White markers for the auxiliary boat lane are there and all detail shown in the online map is all there with regards to the contours, underwater features, etc... I can't find any setting in the unit that would hide/show these markers. They just do not appear to be included in the data even though they are shown in the online map...

It is a bit disappointing to have such a major navigation feature missing in a product that is intended to aid in navigation...Any help finding out why the markers are absent would be appreciated.

Thanks!

Were you viewing Nautical Charts or Sonar Charts (FishNChip)?

Do you have all the Chart Details turned on?

Thank for the quick reply.

When I downloaded the data to the card from Navionics, I selected all three available choices. They were Nautical Charts, Sonar Charts, and Community Edits. All three items appeared to properly download.

In the Elite 7 menu, I have a selection for chart data of "Lowrance" or "Navionics". "Navionics" is selected. Also checked are the boxes for "Waypoints", "Routes", and "Trails". I do not see any other settings where other map details can be selected ON/OFF.

Note that the auxiliary boat lane marked by the Red/White circle show up, but the Red/Green north and south markers are absent. If there is a setting for map details to show/hide, I figured that all of these markers would show/hide together.

I use Humminbirds. I just downloaded Toledo Bend to my Navionics+ card for Nautical Charts and Sonar Charts.

All the markers are on the Nautical Charts.
The boat lanes are not on the Sonar Charts layer and some of the channels markers are not either.

I am looking West of Turner Creek on the main lake. My map curser is at N31 30.665 W093 43.914

Some runs have Red and Green markers and some have just Red ones.

If you have Sonar Charts (FishNChip) layer turned on, turn it off and only use Nautical Charts.
Nautical Charts is Navionics data, Sonar Charts is not, but has some parallel features. Getting the same features on both is a work in progress.
