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

It is very possible. Thanks for the info. Maybe I`ll try it on my 760 someday.

@ddabcd277 -- I can also confirm that your file works perfectly (despite the "error" in sysinfo. I suspect there is some checksum bit elsewhere that was based on the original splash and is not being updated).

So is the only difference that c0 byte (where I had d0)? what is it for and how did you figure it out?

I am impressed ...

Thanks!
