Raymarine C80

[Pete7]

Geoff,

If its similar to the 125, then there are 4 or 5 very small cross head screws which go upwards into the top cover. Without taking these out you will only damage it. Once the top is of, I think the circuit board then needs to come out. I seem to remember ending up with a dish of 7 or 8 screws by the time I reached the batteries.

Might be worth a phone call to Raymarine before you start to see if there is a battery inside the 120 series.

As for the screen, be careful that coating is known to be fragile.

Great! Now I find out. I had to dump a Raymarine GPS last year for these symptoms. To think it was just a couple of cheap lithium cells. Replaced it with a Garmin 117 which is working well and far less expensive than a Raymarine unit.
