Any user looking for a SirF 3 device, please make sure you either purchase a model with newer firmware (above 3.0.0) or the solid promise you can upgrade it to a newer version by yourself.

SIRFIII's have a couple of REALLY ODD PROBLEMS when they're fed with the older firmware (no fixes, spontanious loss of fix, long time needed to get a fix after the previous was lost also known as "jetlag").

The Yakumo DeltaX is a PDA with the SIRFIII incorperated. People who have problems with their machine, please note Yakumo has put a fix (it's a Sirf3-firmware update) on their site : only then will the DeltaX work properly.
Make sure that whatevern SirF3 you buy, you have access to the newest firmware, otherwise the machine is virutally worthless !!!!!
