hi i use this one since last year , my settings are com port: COM4
baud rate: 57600
DOP 0.7 on clear sky .9 on a cloudy day
i carry it on my hand or in the pocket, i recommend and arm band.
the zigzags and other weird stuff that happened when it has windows managed configuration
for my firrt gps fix i wait no more than 1 minute or even less
how do you carry the X1? - i found it best vertically and not too close to my body.
how long do you wait before setting off for your training? - start giving the GPS about 3 min after the first fix.
what ist your setting in "setup" - "configuration" - "GPS config" - "GPS Dilution (DOP)? - take this down to 5 or less.
I have a htc tytnII and when using the internal GPS I have also experinced cases where the recorded track was completely off, but it was due to the GPS going totally wrong. So now I'am using a very good external bluetooth GPS ( I got cheap from ebay). I will still use the internal GPS for when I'am car driviing. when car driving the internal GPS sensitivity is good enough to give me direction but for running, biking the internal GPS can go wrong if the conditions are difficult (cloudy sky, etc...) .
