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

Touch screen does not work

I had the same problem.
I fixed it by running the battery completely down.

Leave it on until it shuts down, then turn it back on till it shuts down again.
Repeat this a few times to make sure the battery is completely discharged.

After that, I plugged it into a power source and it worked fine.

My Garmin nuvi 1300 brightness problems

I spoke to Garmin Support about this issue. There are 2 settings for contrast on the nuvi 1300. You need to set the contrast while it is plugged into the vehicle, and also while it is unplugged from the vehicle. The reason for the 2 settings is to save the charge of the battery while it is not plugged into the vehicle or power source.

Garmin Nuvi 660 shutting off

It sounds like your battery is defective. They can be replaced. The Motorola phone cable is not wired exactly like the Garmin, and your Nuvi thinks it's connected to a PC. Radio Shack carries a charger for the Nuvi. I have one myself.

Let me know if you need additional help with your battery problem.

Light is dimmed. Cannot make it brighter.

This happened to me, too, when I replaced the battery. Turns out one of the wires that affects the brightness came loose. I found the loose wire, touched it to a few places where I thought it should go, and one of them caused the screen to come on to full bright.

I was extremely nervous dealing with this - never soldered in such tight quarters before, but once I soldered it down, the problem was solved. I have other problems with my ique - like extremely limited battery life - but the brightness problem is solved.

It might be that the screen has gone dark due to overheating (was unit in bright sunlight?). If you look carefully, the screen may still be on - but very dim. Go thru the menu until you get to display and try to reset it to a brighter state.
