nav net



My Navnet, I have the one before 3D. It has locked up 2x in the past three weeks. Software is up to date. Also, when this happens I lose my Robertson auto pilot. Reboot and everything comes back ok.
Please provide the full software program number. Also, please provide the information about your chart card (type/part number, date, coverage area). What exactly do you mean when you state that the NAVnet locks up? Is it completely unresponsive or can you change display pages? When you press buttons, does the NAVnet beep? What do you mean when you state, "I lose my Robertson auto pilot?" Does that mean the data from the NAVnet stops getting to it or that the Robertson shuts off? How do you have your Robertson connected to the NAVnet?

I called and talked to Jeff.Who right off the top of his head had the answer.

The answer has two solutions:
1. turn off tides and over powers the RAM and locks up

2.upgrade from v2.07 to 2.11.This turns off tides and currents after 20 minutes.Look at the fixes and you will find this as an item that is fixed.

FYI and Thanks
