Navionics

Does anyone have a navionics plus on their Lowerance?
My navionics quit populating the screen and wanted to see if anyone had a chip I could place in it to see if it is a chip or unit problem. My computer is at my house in augusta. I am located at the neck. If anyone could, pm me please

Mine has been acting up now for a while. I had asked this question a little while ago and the general consensus is a little bit of moisture getting in there and causing the unit to not read/identify the chip. I need to take the chip out of the unit and re-insert and that has been working for me.
