I am the proud new owner of a 2000 Catalina 470 with a full Raymarine system. ST80 Masterview, 2 ST80 Multiview, RL70C Plotter, Type 300 Course Computer for the autopilot. While cruising this Summer, the Heading Sensor seems to have lost its calibration. About 150 degrees off. On the plotter, looks like we are dragging the boat backwards, so the predictor line is way off, and the look ahead feature on the plotter doesn't work. Today I worked through all the setup menus and can't get access to the compass linearisation or the offset adjustment. The icon on the right button just shows a blank square. Went to the Pilot Calibration section to make sure the Cal Lock page showed the page as Unlocked and saved settings. A call to Raymarine was very unhelpful. He walked me through a couple of things and gave me some resistance values for the wires to the heading sensor (they were all fine) and then everything was no, no, no, and no. No we don't support the ST80 anymore, no we don' have any manuals or information online, no we don't have any techs around here that know anything more about the ST80, and no there is nothing more I can do for you. If Raymarine can't support expensive systems that are only 7 years old, it makes me reluctant to recomment Raymarine or upgrade my system. The heading sensor does seem to work. Values change appropriatly when the boat makes a turn, or when I take the sensor off the bulkhead and turn it manually, And no, there is nothing ferrous near the sensor. The tech did say that the offset value is stored in the course computor. The calibration page on the Masterview just shows a value of ---. I just can't get to it to change it. Long post I know, but there are a lot of important details to get by all the obveous solutions. Does anyone with experience with this situation have any solutions?

Check Master/Slave and wires
I have a different Raymarine system and had a similar problem....twice. I do not have them integrated though and that is a big, confusing issue with Raymarine setups. The first time I found that a wire was broken inside the insulation right at the conector. No signal to tell the unit weather it is a master or slave. The secobd time I found that the unit was set in slave mode which means that it must be calibrated (linearized) at the computer and not the unit itself. I don't know how the setting changed but assumed I did it because one wrong hit on a Raymarine button can send you into "what's up" land. All Raymarine owners have the same issues....good stuff but expensive, confusing manuals written by engieers for engineers, and little or no factory support. I'm not sure if this will help but hope it gives you leads. Good luck TC

Thanks for the replies
Thanks for the replies. I had already found those online manuals for the ST80 and also for the Type 300 Autopilot controller. No clues yet. Last night I tried the compass setup from the RL70C plotter. In a data box I show a heading of 137 degrees when the physical compass is at 315. When I try either the linierization or the deviation setup, the Plotter displays a "Warning No Compass Detected". But when I pull the fluxgate from the bulkhead and rotate it slowly, numbers in the heading databox change appropriately. Very strange. The plotter shows a compass heading, but in setup it can't find the compass! Any more help is greatly appreciated

Technology End of Life Scenerio
The only potentially helpful advice I could offer is that you find a local installer and ask them to come recalibrate everything for you. You just need to make sure they've been working on Raymarine gear for more than 7 years. As a side note, having been in the technology industry for the last 12 years, I can tell you that it is very normal for a company to EOL products. It's hard to expect them to continuously train their staff on every product they've ever sold; not to mention stocking replacement parts going back many years. This is why I suggest you find an old salt to help you recalibrate everything. Atleast the new stuff is built using standard ethernet and the software is not tying you to specific hardware. ie; you can load Raymarine onto your laptop, use a standard flat screen monitor from Best Buy, etc. This allows you to simply upgrade the software, and if needed, replace the brain instead of the entire body.

Gyro
had a similar problem, ends up the gyro was mafunctioning, when i took it off line everything worked fine,the fluxgate compass was ok, just the gyro screwing things up, I guess it makes for better overlays etc, but cp, auto pilot etc work ok without.

compass
here's the link to Raymarine's troubleshooting page for the fluxgate compass. interesting that the fluxgate is off by about 180 degrees. kinda hard to mess the connection to the course computer up. so might want to check this page. Bryce
