So,  I'm have a problem that I hope someone has had before that can help me out.  I have a 997c on the bow with no gps puck and another 997c at the console with a gps puck attached.  A month ago while fishing my gps quit so I swapped head units and still no gps.  I ordered a new puck figuring that I had isolated the problem but when I installed the new puck I still have no gps with either head unit.  While I was waiting for the new puck I downloaded and installed the latest software because they told me I had to for the new puck to work.  I now have no gps and only at the console no matter what head unit I have they work(no gps) but after about a minute both units keep going back to the loading and then the screen that I have to hit exit.  I'm now thinking maybe I have a power problem at the console because both units work on the bow with no puck attached.  Does anyone have any recommendations?
Thanks in advance!
