Maybe now they have a branch in SanYa.

You can try the module out with a handheld old gps, which outputs rs232 signal to pc
Yeah, but my old serial GPS units need to be outside to see any satellites, and still take at least five minutes to acquire a position.

The new ones are incredibly sensitive, even indoors, and get a position quickly (and they are tiny and low power). My oldest GPS is the size (and weight) of a friggin' brick.

You can also test serial devices by connecting the TxD and RxD wires, and checking for a character echo.
