The first questions: Where you got RGN files? Are you sure what they is for your ID of device? Nuvi 2x5 have a 4 different models and each of it need for properly RGN - Nuvi 255, Nuvi 255 MTK, Nuvi 255W, Nuvi 255W MTK.
The second is warning: If you Nuvi have the software of 5.10 and above now when you "successful" load a version 4.60 RGN to it you would get the one outcome - your Nuvi would be died.
