May depend on models. The ones I looked at said repeatedly press the power button to cycle the backlight.
Anyway http://www.garmin.co.uk for the manuals

Change LED ... is the machine capable of driving a more powerful LED ? I suppose the gain control might help ? I'll elect to leave mine alone - but wait to hear about your success ??
[/ QUOTE ] The gain control wont affect it, thats just a sensitivity control on the amplifier. It depends on the transistor driving the led. The circuit diagram in the manual does not give any details. Maybe the resistor in series with the LED will have to be changed but if the transistor is not capable of powering a brighter LED then choosing an alternative will be beyond me.
I might give it a try sometime. If I bu**er it up I'll have a reason to buy a nice modern one with a digital display, otherwise the old Seafarer 3 will see me out no doubt.Sea Wych Owners Association: www.Seawych.org
