Guest Posted April 20, 2010 Share Posted April 20, 2010 Our boat came with a Navman 5600 chart plotter which a good friend of mine also had on his last boat and says it was brilliant. However there was no chart in the unit when we got the boat. Back in January at the Boat Show we bought the appropriate chart but only finally got around to fitting it last weekend. Alas the chart plotter does not recognise it. Sunday afternoon we had the opportunity to exchange the chart card with a fellow forumite who lives in the neighbourhood and owns a shiny new Horizon chart plotter. We discovered that a) our chart worked fine in his Horizon and his chart didn't work at all in our Navman. Any suggestions as to a course of action? I've inspected the contacts and they are shiny, clean and properly positioned so the implication is that the plotter is somehow not talking to them at all (broken solder or something?) or there is some larger issue with software having fouled up (though it works fine in all other respects). At the moment the plan is that my friend who formerly had the same unit himself (and still has the pieces of one at home) is going to take it away and check the joints etc. If that doesn't yield anything then it's a bin job. If anyone has any other ideas then I am listening.... Quote Link to comment Share on other sites More sharing options...
