Garmin GPS 10x is a GPS receiver from Garmin, widely used together with smartphone and PDA, which is paired via bluetooth. The advantage of using GPS 10x is that we can use the free version of Garmin Mobile XT (GMXT) on the smartphones/PDAs, while we have to use the paid/SD card version of GMXT to use non-Garmin GPS receivers.

It is using the newer SiRFstarIII GPS technology.
