I fitted a new Raymarine C90W plotter as part of an electronics upgrade at the beginning of the year. The advertising blurb made a big thing of the internal GPS sensor and the integrated Navionics charts. I quickly found out that the charts weren't worth much and purchased a Navionics Gold card. My local chandlers said the internal GPS should work fine, but i called Raymaine as well, for a second opinion. The guy from Raymarine asked what my boat was and then told me that it would be fine, as they had carried out lots of testing on boats just like mine.
When i fitted it, it worked fine, very well in fact. But, the last three weekends it hasn't worked so well. On startup, it's taken a long time to get a position fix. This Saturday it took 38 minutes to get a stable position fix and while we were at anchor 12 miles offshore, it lost the fix a couple of times. Sunday morning, before we left the boat, i switched it on for a while and it worked straight away. Spoke to Raymarine today and they say there are no known issues with the internal GPS units. I'm wondering if perhaps recent weather/atmospherics might be the cause and the internal antenna isn't really reliable. Raymarine have suggested a power on reset, returning the plotter to factory default, sounds a bit like "please re-install Windows"
I'm certainly not going to be very happy if i have to fork out over 200 quid for an external antenna to get a stable and reliable system. In my mind, that makes the plotter unfit for use, i bought it to use in my boat, with the supplied internal antenna. With this and the problems i had initially with the Navionics cartography, plus still waiting for some software updates to allow PC networking with the plotter, i really am wishing i'd have bought Garmin instead.
Anyone else have any experience with these ?
