A mate of mine is on his 4th Garmin 3006C plotter, 'cos the original unit and all its replacements were continually misting up. This latest one is now fine - it's been in the boat for a few months with no problems. Garmin have finally sorted out the screen seal on these, so I decided, as I have the same unit, that it would be a good idea to change it, as it's also suffered the same problem since new.
I had a chat with a nice man on the Garmin stand at SBS and he arranged for me to return the unit and Garmin agreed to send me a replacement unit with the modified screen seal. This arrived today and I've just finished fitting it to the boat. Hopefully, I'll get a chance to try it out on the weekend.
So, what's the point in all this rambling nonsense?
"Garmin for me everytime"
