Thread: City Navigator® North America NT 2010.30 -IMG Locked&unlock+ Mex&Can IMGs +mapsource version

please forgive me for my ignorance. I have searched and read the How-To's.

I have a nuvi 255w and want to update the map to the .30 version.

Can I simply use MapUpload to do this? I have read the FAQs and it says to copy the .30 .img into the Garmin folder, but everytime I do this, it says it cannot copy as the device does not have enough memory.

I have renamed appropriately as well and tried to use SD card but it doesn't do anything, even after restarting the 255w.

Thanks for your patience and help!
