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

I suppose others who follow this thread would like to know, so this is not spam

The single image version works fine for the "splash", and is replaceable via the "display" menu. The problem is that after the splash, when the copyright info and "load maps" message are displayed, the background becomes what I think a garbled version of the splash (this is verified when I replaced the slash with another picture) -- the effect seems being that the dimensions used for the display are incorrect.

The double image (in which the second one is a flipped version of the first one) version also works as splash, but cannot be replaced (unit hangs if trying to replace), and the "load maps" display has a mostly dark background (but at the right angle one can see that is a hint of a garbled splash).

I'll try to take the screenshot, but they are really just like what I described plain and simple.
