Navionics help

[tillerybass]

I have finally installed the navionics upgrade in my hds system and everything worked fine. But then when i put the navionics card in, all the maps show up like they should but then they disappear in about two minutes and the screen goes white. The only way to get the maps to show up again is to go into charts and switch it back to Lowance charts and then back again into Navionics, but then the same thing happens again. I do not know what is wrong.

Thanks!

A friend of did the HDS software install and has problems with Navionics also. Maybe if enough complain to Lowrance, they will fix it with another software upgrade. Typical first year product release from them.
