When I purchased the Raymarine e-series for my boat last year it came with their Lighthouse charts. I could never get them to work so I just installed Navionics charts and are happy with them. I have updated the Navionics a couple of times while the charts are in warranty. Does anyone relay on the Lighthouse charts? What advantage do they offer? I want to know if it is worth my time to try to get them to work. The Raymarine installer seems to pretty well dismiss them.Thanks, Joe
