Thread: Multiple Maps on NUVI 200w/Nuvi 255W sd

I did check the first post from OP.
It does not specify the OP is using a U.S. 200W HWID or firmware.
But the OP is using a U.S. map, so it does indicate that it is most likely being used with a U.S. HWID firmware device.
Therefore (especially as being Tutorial thread), it is highly relevant to mention details such as only the recent U.S. HWID firmwares support gmapsup1.img for these 2xx devices (and some other legacy U.S. nuvi devices).
