@Neil,

I was not offended (all is well) and just wanted to clarify further details that gmapsup1.img is not supported if using Asian firmwares on 2xx devices.
Although the U.S. 200W can have 1 or 2 GB, I'm unaware if all (or any) Asian HWID 2xx's have a 2 GB memory or not.
My 1 GB nüvi 200W U.S. HWID 737 is now using v4.10 that supports the gmapsup1.img.

By using TurboCCC's RGN_Tool, I enjoy some added features (not available w/the U.S. firmwares) buy using Asian firmwares on my a U.S. nüvi 255W w/SingMal v3.10 firmware and a U.S. 775W w/TWN v3.30.
Wishing that Garmin would also update these Asian firmwares with support for using gmapsup1.img as well.
