Charlie is right I have a SH combo unit(5") and I was able to get rid of those boxes for the same reasons you want to.
Thanks for that Rob.
I sure hope you're right.
I read Charlie's post...
"From page 35 of your manual:
2.20.0 Selecting Data Window layout
Press “MENU”, select GENERAL SETUP from menu, then press “ENTER”, select DATA WINDOW and press “ENTER”, select CHART PAGE and press “ENTER” again. Choose the desired data window layout to be shown with the ShuttlePoint knob and press “ENTER”. Selections are None, 1 Line Small, 1 Line Large, 2 Line Small, Highway, Compass. See previous Figure 2.20.
Select "none". "
He must have a different manual than me.
Page 20 of MY manual is all about wiring and DSC Connections.
On page 59, I find "10.0.5 Customizing the Data Windows".
The passage reads...
"The data fields contained on the General, 1 Line small/large and 2 line small data windows can be changed. The picture below shows the Chart Page with 1 Line Large selected and
a Popup window with many selections.
1. To change a data window field, press and hold [MENU] until the field is highlighted.
2. Move the ShuttlePoint knob to the desired data field and press [ENTER]. The popup
window will be shown.
3. Move the ShuttlePoint knob up or down to choose the desired setting and press
[ENTER] to select and press [CLEAR] to store and exit the editing mode."
In the middle of page 60 it reads
"
NOTE
Data window field on the NAVIGATION, HIGHWAY, GPS STATUS, and NMEA pages may be
customized in the above manner."
No mention anywhere of customizing the fishfinder display.
I've also got a completely separate manual for my FF520 black-box sonar module.
No help there either.
When I get out to the boat I'll try again but so far the manuals aren't helping.
