Title: 1197-Chartplotter window scale keeps changing on me
Post by: nediver on July 16, 2021, 04:46:04 PM

Hi All,
Once I enter  Lat/Lon of a target I want to dive and drive the boat towards it I generally set the chartplotter window scale to view where I am to say, 1,000 feet. As I get closer to the target I drill down for an expanded view to say 500 feet, then 100 feet then 20 feet etc..

For the past month or so I'll have it set at say 100 feet and all by itself perhaps a minute later it moves to 500 feet. It is doing this all the time.

I did the 2 re-format moves and that did not solve the problem.

Any help appreciated.

I got out today and pulled the Navionics card out.

Machine did the same thing-no change at all-range setting changes all the time.

Any other ideas appreciated.

Under the Setup tab set User Mode to Advanced  ...

Then look under the Chart tab for Auto Zoom and Auto Range. Make sure both are Off

Yes! I followed the advice above and changed the setting but it didn't work.

I then read another post that I  should do both of these: Change AUTO ZOOM setting AND change AUTO RANGE settings and it worked. Was out for 4 hours yesterday and the Bird worked great-no issues.

Thank you everyone I really appreciate your help!
