Question about Garmin Nuvi 660 GPS Receiver
My 660 screen is brighter when running on battery then when it is plugged in. I have tried everything that i know of. and i cant seem to get the info from the manual. I set the screen timout to off and it still does it.
Mine the other way round, brightens when plugs into power source, but only marginally, enough to notice it though.
think is probably a characteristic of the electronics
