orly? Take a good look at this picture. [Only registered and activated users can see links. ]

This is the logic board of the nuvi 205. like I said before: it's basecally a computer. It has an OMAP processor, a nand flash that stores the firmware and maps, a sdram memory module.

"System memory for the processor comes from 32Mbyte of DDR SDRAM from Hynix Semiconductor Inc. for working memory and 2Gbyte of iNAND flash from Sandisk Corp. The latter holds all mapping data and system codes (for download to DDR SDRAM) with the inclusion of a NAND controller to manage the host processor interface. Wear-leveling and error correction along with SD or SPI bus interface formatting are all handled in the controller chip, copackaged with what is almost certainly multilevel-cell (MLC) NAND silicon."

All the units from garmin have basically the same design. They only add more modules (like bluetooth and tv) and more memory, and sometime a bigger screen.)

So don't come here and say I know little about my unit. It's all software based dude. Theres no secret kill switch inside the hardware. Garmin wins money with they software (one of the best available) But even they software is almost the same in all units of the same range, with a few modifications.
