Zachary 2 Posted November 8, 2017 Share Posted November 8, 2017 Hi all, I have inherited a Navman 3100 multi on a new boat - which displays a couple of part digits and nothing more. I recall there was a bunch of noise about these awhile back but can't find anything. In anyone's experience, are they repairable? Are they worth repairing? Is there anyone with spares?

marinheiro 352 Posted November 9, 2017 Share Posted November 9, 2017 Check out YouTube, there are a couple of videos there showing how to replace the faulty ribbon tape with a conductive strip. Quote Link to post Share on other sites
Changed 10 Posted November 10, 2017 Share Posted November 10, 2017 I have a brand new speed unit if it helps. Still in box. I needed the paddle wheel! Quote Link to post Share on other sites

Fogg 427 Posted November 13, 2017 Share Posted November 13, 2017 I've done 2x repairs of the 3100/s and so when mine finally crapped out again last season I decided it's time to call it quits and replace the whole system. So I'd caution about repairing because from my experience these units are beyond their natural lifespan and it's diminishing returns! Quote Link to post Share on other sites
Zachary 2 Posted November 13, 2017 Author Share Posted November 13, 2017 Thanks all. For $50 odd I'll give the repair a go. Quote Link to post Share on other sites
