Location: Eau Claire, WI | I have a head scratcher. I use expert gps to manage my waypoints. I backup the data off the 520C then divide out by lake on the computer. Expert gps saves as .gpx files. When I want to put lake specific stuff back on my units, I "send to gps" which converts the .gpx files to .usr. I put the card in the machine and load the data.
Been working great for a long time but something has changed.
Now when I try to load this data, I get an error saying that it cannot load because selected mmc card or harddrive is full. That is not the case. I have two 520C units with the same problem. Both are running v. 2.5.0.
So now the head scratcher - I take the same card and put it in my HDS5....LOADS THE SAME DATA NO PROBLEM!
I'm starting to think there is a problem with the system software on the 520C unit and it won't read any .usr it didn't create. I say this because every one I try to load fails but when I back up the data that is already on the 520 and try to load it, works just fine. I even replaced the SD card just in case there was something wrong with the cards. Didn't make sense that it would be but tried it anyway.
So I'm out of ideas. Can't find anything online. Lowrance's support site didn't yield a clue.
Anyone else recognize this and know what's going on?
Thanks,
Jono
