Why are you so sure that phone book, etc. isn't stored in the filesystem? Did you check all the .db files which are just SQLite databases? Security is a bad argument, as firmware can encrypt any data on the filesystem. non-volatile memory isn't secure also, as we can easily read it, write it and decrypt it.
kunix don't confuse me! Special for you I replace ROM to non-volatile memory! Nice to meet a worthy companion on amateur forum

No phone book and other personal data stored in file system that open for usual user! If you find anything trace of it in files you must urgently send a message to Garmin. It is the serious vulnerability!!!

But I agree that non-volatile memory isn't secure also. But it is more secure than usual file system. I hope you know what deleting of file it does not mean the physical removal of info from media.

P. S. You is very young but I am remember a great collision with the one of version software of Nuvi 660 when any can read another's phone data after pairing with other phone!
