What dialect of Chinese?
My TomTom has a free Cantonese voice-over that you can download right out of TomTom Home.. But I think it doesn't speak street names or anything like that.. Street names are always done with the GPS's english voice. There are also dozens and dozens of Spanish voice-overs that were done, some good, some not so good..
With the TomTom, you can do your own voice over.. You just record your own voice saying things like "left" "right" "ahead" "turn" and so on, and it will use those if you want.. So you can have your directions given to you with your own voice.. Or your wife's voice.. Or your children's voice or whatever you want..
I think the Mandarin Chinese for Tomtom costs a bit of money, $20-$30 or so.. You can browse and buy it right from Tomtom home.
Edit: To be more specific, the only updates you get for free with TomTom are when there are mistakes in the map (where the Tomtom thinks a 2-way road is really a 1-way )..You can mark a map error, fix it yourself and then share it with other people.. These are called "Map share updates".and are only updates that you share with other people who have the EXACT same version of the map. When you plug the TomTom into the computer, you get all the latest mapshare updates for your map automatically.
All new roads, bridges, constructions, etc. require you to purchase a new map to get them, but TomTom does offer an update service where you pay a monthly fee to always have the latest map..I buy a new map once every 2 years, the free map share updates are great.
Onboard RAID vs. 3Ware RAIDI never recommend people run RAID-5 with onboard chipsets.
