I'm sorry to hear about the issue you are having, I will do my best to help you resolve it.

We need to reset the unit, and then update its firmware. heres how to do that.

First, the reset process

And then, to update the firmware go to this link

Download and install the newest version of Garmin express, and then once installed. Run garmin express and install any and all updates it shows for the nuvi 255. Once complete, test the unit. Is it working any better?
