				I just installed the 6.740 update.  In the simulation mode my screen goes blank when viewing with 83hz.  It works in 200hz and 83hz/200hz.  Any thoughts?  Thanks inadvance

				I don’t have an 898 unit to try this on, but I did update a 998 unit with the 6.740 software and the 83kHz works fine in the Simulator mode.

 There are symbols of fish?

				Tried it on the water today and it seem to work just fine but if I have my SD card (with the update on it) all the screens are blank.  Once I take it out then all screens work.  Just really weird.  I will keep tinkering with it.

 I had to check navionic but yes, there are Fish ID Symbols when the unit is set to display the 83kHz sonar.
