When the yard hauled Shiva they managed to part the very thin antenna which connects the GPS "antenna" to the below decks unit. I called Horizon to see if I could splice it or replace it. Answer: NO. Antenna needs to be replaced and the cable cannot be spliced.

Considering that it costs $90 to replace and the unit is 10 yrs old, I'm going to replace the entire unit after I attempt to splice the cable. It was a back up anyway. I can get a newer replacement which reads to same chart chips for $369 or a much newer version for $650 which reads the same cards.

Or maybe I won't get another plotter, but an AIS with a GPS output and feed that old plotter with a GPS position from the AIS etc etc and so forth.

I need to deal with the nav station which wants to have something where to old plotter would be if it were to be removed.

What would you do?

Search EBay and Craigslist for a used one.
