When you connect nuvi on win7/8 pc they ask you if you check disc or if you go to nuvi with no check, and you just click with no check.

You will see, that on your nuvi desapire some files or this files will be in some different folder.

I see a lot of nuvi when user say that he only connect nuvi to Pc and add map or poi on nuvi and after this nuvi wont boot anymore.
When i ask him this: do you have win7/8 and do you click on check disc when Pc recognize nuvi, answer was 2x Yes
So, no problem with map or poi but problem was becouse user run check disc.

How do i know this, that no problem with poi or map?

I run cure FW and create backup of map and poi, format nuvi, download files with webupdater and add back the same poi and map and nuvi work like charm.
