[CA] [CA11] Wirless system and compass selection

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Tom,

This is very odd indeed. Please note that the p70/p70S/p70R/p70RS autopilot control heads are not designed to show the latitude and longitude. Please list all of the other marine electronics devices within your system. Regarding heading, lease be aware that unlike other currently manufactured Raymarine products, the TackTick products cannot support multiple sources of any one type of data. As such, removing the TackTick compass would have indeed been recommended within your system. I have been unable to duplicate the problem within my own system. Please use the Diagnostics feature of the p70/p70S/p70R/p70RS autopilot control head to determine the following:
- version of software installed within the p70/p70S/p70R/p70RS autopilot control head
- version of software installed within the EV-1 CCU
- version of software installed within the ACU100

Please additionally specify whether Wind data is being populated when configured to be displayed on your autopilot control head. If not, please additionally specify whether the MicroTalk's LED is illuminated and if so, what is the LED's color.

Regarding the heading difference reported, heading sensors must be calibrated and then aligned. When aligned to a known bearing (such as that which would be accomplished via range marks, etc.), then it would be expected that the heading reported by the sensors would be fairly close, when configured to the same reference (True or Magnetic). That said, the heading data performance of the EV-1/2 is vastly superior to any magnetic north seeking device which Raymarine has ever offered.
