Default Trackball on Navnet VX2

Just bought a used boat with a 2007ish navnet VX2. My pointer goes side to side but not up and down. The trackball moves but feels a little gritty.

There's a ring around the ball that looks like it could be turned and maybe allow removal of the ball for cleaning. True? Can I clean in there?

If I can clean the ball, rollers and sensors what's the chance it will fix my problem?

If this puppy does have to go back to the factory I guess it won't be all bad since there's probably newer firmware available for a unit this age.

Just give the retaining ring a counterclockwise turn a few degrees and it comes off and the ball will come out. You can turn the rollers with your finger to determine if there's an internal problem. There are parts in the back of the retaining ring, (foam gasket, spacers and a plastic ring), that cause nothing but problems. Very poor design IMHO. You can get a new trackball with retainer ring from Furuno for around $65. You can update the firmware yourself by downloading from Furuno to a blank SD card.

Thanks Eric! I just read the manual and it mentions the removal and cleanup. (When all else fails WTFM!)

Hopefully this will fix my problem. I'll check out the firmware on the Furuno site as well.
