Yes the Nuvi has this, When you use the Nuvi on Battery it will safely switch off when the battery "If I'm Not Mistaken" Gets to about 3%
We are takling here about someone switching on a Nuvi that has the battery almost flat.
The symtom is that it gets to loading maps and then crashes and switches off sometimes the crash is logged and sometimes not.
I've had this happening on 3490 and had to flash region 41 via SD card to fix it.
I keep backups of regions at every firmware level. "OOPS I havent done it for 8.1 yet"
