I have a simrad wheel pilot about 4 years old.
Last year the belt broke, called simrad they said they don't support that unit anymore and did not have replacement belts. after about a week of searching on the internet I finally found them & bought a new one and a spare.
3 weeks ago hit the tack button & started going in circles got it to stop but now only wants to track south. So if simrad doesn't support wheel pilots where do you send it to to get repaired.
I should have gotten the Raymarine version the extra hundred bucks would have been well worth it (I also replaces my instruments this past year ... with Raymarine so if they have a problem 4 years from now I can get them serviced)
