Saw your post and searched out the update which was finally emailed to me by Lowrance.
First call did not go well, but on the second call I got Craig. He seemed to live and breath this stuff.
Anyway, instructions for posting files would be helpful if there is a way to post them here.
Otherwise, I would be glad to email them on to anyone who would benefit.
I am in search of the original 5 pin networking cables (blue ones 5 pins in a star pattern).
Just need one end with male pins and I will be able to wire up all the devices I received in a box.
Planning to link the 2000 gps antenna to the 3500c and share data to LCx-15mt.
