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?

Hi,

I also have a nuvi 205W from USA - FW 7.5, HWID 1091, S4. Will this method work for it? Also, it seems these updates will remove ecoroute from the device. Please advise.
Thanks.

This guide is for mainboard version S2 & S3 only.
This does not work with mainboard version S4, you'll end up with a white screen and brick your unit!

You have S4 so... no-go.
