Now if I have succeeded, had installed the plugin Notepad but could not install it.

first use the other program ...

They are doing a cure at a Nuvi 255w and can not enter in pre-boot mode

The problem if I take the Target esque keeps restarting even if you have the button depressed, to stop it I have to put the memory SD with the SD set starts well, but even if you have not stepped on the button goes blank if not that follows its normal boot process and not recognized by the pc
software version 7.20
id. xxxxxx255 / audio version Missing / gps sw version. 4.10b
american language only has the English, has no voice or traffic or radar 20011.32 only maps but only if I put the target
any ideas?
