Hello: I recently stumbled across this thread. I have a nuvi 265W. I am conisdering trying this. These instructions were from 2 years ago. Currently, my 265W (US version) has FW 7.5. Does this method still work? If the GPS is flashed to Singapore FW, will it work with current US Map and JCV? What about FW updates? What happens if I run Garmin WebUpdater on a GPS flashed to Singapore FW, will it re-install US firmware?
