Network problem; sharing waypoints

[Steve Wood]

Todd, I have a NEMA 2000 network set up in my boat with an LCX-25c at the console, an LGC-3000 antenna, and an HDS-5 in front. This weekend I decided to switch the position of my GPS units as I'm going to upgrade the map chip in the HDS unit to Navionics Hotmap Premium to get better detail on some smaller lakes that I'm planning to fish. I haven't rec'd the chip yet, but my understanding is that it won't work in the LCX-25c unit. I have the network powered through the power connector at the console GPS and when I switched units, the network quit working. I researched why and determined that the HDS unit won't power the network so I revised my wiring to get that working again.

My problem may have been there in the original configuration also, but the HDS-5 unit cannot "see" (read) the waypoints on the LCX-25c unit which is where the majority of mine are stored. The LCX-25c can read the waypoints from the HDS. It seems like that is one of the primary purposes of the network; to share waypoints and data. Is this correctable?

One thing I haven't done yet is update to the V4.1 software. I did that earlier and it took away the capability to read my LakeMaster chip. I wanted to get the Navionics installed first before I upgrade the software and I did not expect that to be the source of my problem either.

One other question: is there any issue with having a LakeMaster map chip in the LCX unit and a Navionics chip in the HDS unit?
