Navnet3D positionning problems

Hi,
I have a weird issue on my 2 Navnet displays.The GPS coordinates are different on each display,and not matching the real position of the boat.While the boat's position on the chart plotter on both displays is the real position.
Thank you for helping me with this issue.

It sounds like you might be looking at a data box showing cursor position and not the boat position. If you still can't figure it out, please call our tech support while at the boat and they will help you determine what is happening.

Thanks Johnny i will try to look at it and will let you know.

You are right all is ok now,there are so many options and features on this amazing device.
thank you for your help
