Thread: (Nuvi 660) Is it possible to convert OEM FW to regular one?

ddabcd277 -- You have been a tremendous help. Thanks a lot.

I am not sure if 480x272 should be the size for the 660, but the files you posted for 660/670, although GIR_Editor could not process them, it did show the image size to be 480x272. It might make sense to have a smaller logo image in some 4.3" units because some info is displayed on the lower half of the screen during boot-up. For 660 the info is displayed in white letters with black outline, so I suppose it is assumed to be over an arbitrary wallpaper.

If you could teach me how to determine the size to extract for the logo.bin file (or a pointer to some info about the file format/structure) it would be great. I can give it another try to see if I could actually load a 480x272 logo.

Thanks again.
