Slow NN3D

My NN3D has become slow lately. Check this video: https://youtu.be/PExTWxPGfEI
I press and hold the zoom in/ zoom out button continuosly while the zooming goes on.
What may be wrong, and what can be done to get it more responsive like it was when new?

Hello Gyda,

This might be caused by a number of things. First, do you have the Sirius weather box and is the overlay turned on? what happens when you turn off all the track lines?

Also, what software version is your NN3D right now?

Old Ironsides

No Sirrius weather box, no overlays.
Same slow speed no matter if all sensors are in or out, the same with Maxsea pc connected or disconnected.
Plotter set as master in the system with map installed on plotter.
Software version:1950055-02.11
No difference after track lines was erased.

Although speed is subjective, you have used it in the past and should know. It might be best to send the unit in to have it evaluated it might have a bad internal fan or other issue that should bee addressed.
