Just received new Navionics Hot Maps Platinum for my Lowrance HDS7-Gen2 keypad model. I've downloaded my specific area to my card from my computer and installed it into my unit. I get a enhanced mapping feature but not the satelite imagery. I've chatted with Navionics and went through all the steps. We can not get the imagery to work on the unit. Any ideas what I can do to get it to work? it is the correct card for my area and should work on my unit.
