Re: raymarine gps sounder
This is a common problem if the GPS is hooked up to an electronic heading sensor such as an autopilot. If the heading sensor is not calibrated properly, the boat will appear to be facing the wrong direction.
If you have an autopilot, consult the installation guide and perform the sea trial procedures. That should get your boat lined up properly.

I'm not sure where you would locate "reset to factory specifications". Look for it in the GPS menus (may be in the System) and reset, it is no big deal to reset a GPS, it will not hurt anything.I the GPS is set to back Track.To check this turn your boat around and follow the track on the lake chart.If you and your boat are now going in the same direction the GPS was set on Back Track.
I had to replace a GPS antenna unit with cable. Sometimes, during bad weather or strong sun, I lost FIX on satellites. Cleaning the top of antenna did not help. Unit from Ebay was also a junk. Get a new one after testing display on a friend boat.
The direction of the boat symbol is depending on the compass course from the autopilot. You will see that your GPS course (COG) and magnetig heading on the autopilot differs. Solution is to calibrate autopilot compass. Will advice you to not use course up, stick to north up or heading up.
This may help. Mine has the GPS antenna build into the bracket at the back. I removed the bracket and the unit did not go into the error screen and the sounder worked fine. The GPS would not locate but it has not antenna attached so DOH!! I have orderd a new antenna with the BNC connector and will post if that fixes the problem. At this point I'm guessing its a blow GPS antenna.
Please check if the pilot is acting the right direction ,press +10 key and check if boat teers STB,
press -10 and check if boat turns PORT ,if it acts reverse, see handbook to reverse action.
Verify if compass course in standby is indicating correct course .
Do the calibration procedure as stated in in the handbook (360 degree turn)
If it still not indicate the correct course ,or is frozen, compass or printed circuit is faulty.
Check the resistance between the wires of the compass unit .(see google internet)
With the charts page up, start by hitting the find ship softkey at the bottom of the screen.If that find the boat on the chart all is good.If not you need to check you have a GPS fix. Go to GPS screen and see you are seeing satalites.
If all is good when you hit find ship and the boat disappears again from chart while underway you will need to go into the chart setup menu and see if the screen amplifier is turned off. If off turn on.This is first place to start. Hope that helps
Was the engine running when it shut off? How was the voltage at the time it failed? The A65 will shut down if the voltage drops below 11.2 volts.
Another common cause would be corrosion on the plug where it plugs into the back of the display, or the terminal connectors that attach it to the boat's power supply.
It could also be a bad crimp on the terminal connectors. Make sure connectors are the right size for the wire and that they are marine grade, such as Ancor brand connectors. I also recommend heat shrink style connectors,
I have not heard of any software issues for that model so I am betting it's a wiring issue. However, there is an update available from Raymarine. There were changes made to the WAAS satellites and the update helps it recognize the new satellites. You can download it for free from Raymarine. Copy it onto a blank CF card and plug it into the card slot on your GPS. When you turn the unit on it will prompt you on how to proceed with the update. It will fix any known software gliches at the same time.
I hope this answer helps. Please reply if you have any questions about my response.
