does this work on Sony Ericsson 990i ?

[Absar]

No, it doesnt work on the P990i.. Only Nokia's Symbian devices are supported.

The compatibility chart from the site..

S60 1st edition phones (Nokia 3600, 3620, 3650, 3660, 7650, N-Gage, N-Gage QD, Siemens SX1, Sendo X and X2).

S60 2nd edition phones (Nokia 3230, 6260, 6600, 6620, 6630, 6670, 6680, 6681, 7610, N70, N72, N90, Panasonic X700, X800, Samsung SGH-D720, SGH-D730, SGH-Z600 and Lenovo P930).

S60 3rd edition phones (all models not in the above lists).

GTx does not support the internal GPS of e.g. Nokia N95.

AFAIK, professional GPS signal need to be bought from US Gov and it is far more accurate than the free civilian signal.

Civilian signal have positional accuracy of 30-60 meters(fts?) which can be improved using WASS upto 4-5. You can guess how accurate the acceleration times will be.
