I have a new/refurbished (with original warranty) Raymarine L365. It has temp, speed and fishfinder.<br /><br />The first time I used it, everything worked fine. The next time I used it, the temperature was stuck on 32F. I tried changing it to Metric and it says 0C. I did a reset to defaults and it still does the same thing. I also tried adjusting the compensation but it doesn't change it that much, less than 1 degree. Out of the water it shows 33.4F<br /><br />Here's the trouble - I've contacted Raymarine via their online ticket system but haven't received a response in nearly 2 weeks. The dealer won't return it as it was 'refurbished' and says I need to deal with Raymarine under their warranty.<br /><br />Has anyone had a similar problem w/this fishfinder and knows what it took to get it resolved?
