|
|
Hi, I'm hoping someone here can shed some light on a problem i have with my pda/gps setup.
I have an iPAQ hx2110, TomTom Navigator 5.0 and a GlobalSat BC-307 CF receiver. When i launch the tomtom software it takes an age to get a fix, even with the external antenna connected. Once it has a fix it will lose it again at irregular intervals, sometimes within seconds, other times within a few minutes. It then takes up to two minutes to get another fix.
Tomtom is configured as Other Cable NMEA GPS, set at 4800 baud and connected to CF_CARD GE.
I tried soft reseting the device after plugging in the card, then starting tomtom, and i tried starting tomtom and then plugging in the card and it's still the same.
I ran Winfast Navigator and TTFF on a cold start is 50 seconds average, with TTFF on a warm start at 6 seconds average. Once it has a fix in the winfast software, it will stay there all day, varying between 3 and 8 sats.
To me, this rules out a fault with the card, and points to something in the tomtom setup that is causing the problem.
Any suggestions would be greatly appreciated.
Regards
Steve |

As listed in the first post, the reciever is a GlobalSat BC-307 with SiRF-II chipset. It doesn't have any problem getting a fix in the Leadtek Navigator program, only when using tomtom...TTFF is not so much the issue...it's more the fact that it won't maintain fix when it's got one in tomtom. |

The iPAQ is an hx 2110
Have tried it inside and outside the car. The config screen shows as many as 6 grey bars, it just never gets a lock. I'm convinced its an issue with the tomtom software as a lock is obtained use gpsinfo2003.exe, and also using leadtek navigator...which also gives me a fix in the house! , even if it is a weak one. |
