Just saw this review from across the pond, but Im unable to find a US retailer to get an unit.
It has the new SirfXtrac chipset which is supposed to greatly increase reception by using the low reception satellites.
I found this description of the technology.
o what is XTrac ?
"XTrac is a firmware on the SiRF chipset that will boost the sensitivity of a GPS receiver. It does so by acquiring more signal from weaker satellites to help bring in a stronger signal giving better sensitivity in difficult areas. For example, a normal GPS may acquire signals from 4 satellites with the strongest signals to calculate your position. In the XTrac mode, the GPS will acquire signals from several more weaker satellites (e.g. total 6 satellites) before outputting a position. Thus, the better sensitivity."

There doesn't seem to be too many SifrXtrac enabled "mouse type" receivers out there so I was wondering if anyone has used it in trouble areas like NY, or any other city with urban canyons.
Any comments would be great!
