There are many reports of degraded 2d in the new versions...
If you know what version came on your unit..you can back load that version...

The 2D problem with the newer software is that the pixels become larger and larger as the Chart-Speed increases.
You could run CS = 1 or 2 . . . More so on the older HB units with less processor, xxx7 etc.
I restored my units to previous S/W levels...
