Once tuned and set up, how long could one disconnect power from it, before it looses its memory?

I assume its like the alarms and keyless entry systems we sell at work and keeps memory for like a period of 10 years or so?

Thanks

 

I think it's all flash memory, so as long as the EPROM's integrity is intact, it'll last forever?

Thanks Ted

 

Would it really matter, if you have your maps saved to a disk? Or am I branching off on a different subject?
