Is there a chip I can buy for fork to run the lanes on garmin? Or could I just use pne of the humminbird or Lowrance chips? Im looking for the lance vick boat lanes.

nope,..

There are online conversion programs that can be used to make one that will work. I did the same to convert for RayMarine.

I started with the Lowrance I originally purchased.

could you link me the program you used? That would be greatly appreciated.

Boatlanes is not supported on Garmin and here's the deal...

The Garmin unit software does not support tracks with track-segments(i.e. Track-Segmentation). As a result a Garmin unit will in error connect the track-end-points of the track-segments. Garmin has this on their list of software changes to do. Track-segmentation is supported in GPX, USRv4, USRv5 and KML standards. So Garmin units have a software bug.

Boatlanes for Fork, Rayburn and Lake o' the Pines are track-segmented. Toledo Bend is not and should display correctly.

Second issue is waypoint icons. I'll venture that the icons will not display correctly. Probably default to "blue circle".

There is no magic software to fix these issues.

Tommy Martin's GpsLakeMaps will have same issues on some lakes.

Call Garmin Support and report this track-segmentation bug and maybe they will fix it.

If a Garmin user who has Lake Fork Boatlanes for either Lowrance or Humminbird and wants to work with me to create a workaround for Garmin, then he can PM me with his phone number.

RayMarine has it's own issue. They limit the number of points on a track. I had to break the Fork-Specific points into a separate track, convert them individually, and re-connect. Yeah, a pain in the posterior, but it worked.

The program I used was:

GPSBabel, and I tested in EasyGPS.
