I have gone to the navionics site and see on the web app there shows new contours for my chip. I have done the download to the chip and when I put it in my HDS 8 gen 2 it just shows the old information from the chip like it was when it was new. For example, on the Ohio river around Evansville Indiana when the chip was new there were very few contour lines, now on the web app it shows lots of detail. After the download today, I put the chip in my HDS and it still only shows the very few contours that the chip had when new. I only have this one chip in my HDS units so it is not reading any other chip and it is set to read Navionics not Lowrance. I have the latest software on all units. Not sure if I need to adjust a setting on the HDS, or if the new information is just not being written to the card. When I do the download, the Navionics site sees my card and knows what card I have and I have almost 300 days left to update. As the update goes on the progress bar slowly moves and finally says download complete you can remove card. Im lost. Any suggestions. Thanks
