I am having trouble starting up my nav net 12 inch MFD. It is my only net work MFD. It turns on and shows the Furuno logo then goes into a set up wizard which asks if I want to be in english then shows the master to be off. I re set it to on then hit save and exit and it goes back to the Furuno display and flashes in a purplish red color but will not show charts or radar. I tried reloading the software on a chip and after several attempts the machine did go to the plotter screen but shows no maps, and has X's thru all the radar and chartplotter functions. It doesnt seem to recognize or try to load the new software. Any thoughts or suggestions? This unit is just over a year old and still under warranty.
