1. Turn off your S200, open rear cover, remove the battery, locate the gps antenna position.
refer to f1.jpg
2. Peel the black gps antenna carefully and turn over from left to right. use the multimeter to measure resistance between two electrodes and you'll find it's short-circuit status (~0 Ohms).
Look carefully at the root location of the antenna, there is a black transparent line, at the end of this line,you can find the short-circuit point, cut off this copper chips until the short-circuit point completely disconnected, then measure resistance between two electrodes to determine it is no longer short-circuit (Infinity ∞ Ohms).
refer to f2.jpg d1.jpg and modification diagram.jpg or this (surcart's pic).
recovery the antenna, turn on your S200 and test gps. Enjoy it !
refer to c1 and c2 pics (compare with HTC P3600, left is P3600, right is S200)
c1.jpg is before modify, c2.jpg is after .
btw, tracking speed is faster than before.
d1.jpg is a large pic
d2.jpg is the details after modified
maybe you can do it without peeling antenna off, try to cut the short-circuit position directly if you are not sure you can completely peel off. refer to d2.jpg or s200_p1.jpg(provided by wysxs, thx) or Victor79's pic .
