I have an older model Nav-Net 2003. It is GD-1900C serial# 4390-3515. I have had trouble with the sounder freezing up while it scrolls. I was told it might be my Navonics card. I replaced it and it seems to scroll uninterrupted now. But it still seem slow at any advancements of scroll speed. Also I obtain a lot of clutter on my manual gain past the 15 level I understand at shallow water but it also does it at deep water 200 deg. freq. Could I have a bad transducer? Do you recommend an upgrade of any nature for this unit?
Thank You
