If you've bought a GPS unit in the past year or two there are decent odds it's based on the SiRFstar III
chipset, which has been about as good as it gets since it arrived on the scene a few years ago. Now there's a new chip on the block, SiRFprima, which could have GPS aficionados kicking those SiRFstar III units to the curb. The unit boasts "industry leading" GPS performance, and is the first of its ilk to be able to work with GPS and Galileo
signals simultaneously. InstantFixII -- which promises 5 second start times -- is built in as well, along with 3D acceleration for the fancy new maps hitting the scenes, and the capability to work with external devices like touch screens, DVD players, video cameras and so forth. While no one feature is revolutionary, the fact that SiRFprima will be wrapping up all these features into a cute little package for GPS manufacturers to slap into their units without a worry -- which should start happening in the second quarter of this year -- is surely cause for celebration.
