There is no support for JCV written into US/EU firmware for nuvi 2x5W devices. Only certain Asian fw support it and if you have a Western 245W (only with HWID 0827) and a suitable board version it can be safely converted to SG/MY .... but there is risk of bricking permanently to a white screen if you are careless or unlucky in the conversion. Read all of this thread so you understand. You will also have some difficulty when using Western voices, so imo frankly it's not worth the effort and risk. HWID 0827 > nuvi 465T as discussed in the most recent posts is safer, easier and works for Lane Assistance but not Junction View.
