On my TomTom One 3rd Edition GPS Chip GL1 (navcore 9.541), i have got same problems.
Time changed to 00:00 (and doesn't change) after syncing with satellites.
I thought the navigation was still okay but on some trips, I have started to have unstable navigation with my GPS position being from time to time shifted from 50-100 meters, which totally screw the navigation.
Having latest GPSfix only solve the navigation for few days. I have to update latest satellite positions to have a more stable navigation.
I really hope that someone find a solution for GL1 (or could make a new gltt file). A german guy has asked in TOMTOM forum if he could access the gltt code source. No answers yet...
or if someone knows how to create a program that convert data recevied from the GL1 to NMEA messsages.
According to navit website,
- This gltt file is a driver named "gltt" which translates the gps messages into real NMEA messages.
- gltt write to the named pipe /var/run/gpspipe - gltt is called like this sample: gltt -baud 115200 -periodic 1000 -fix_start normal -rftype HH_4L
Does someone know how to access in telnet/shell the tomtom?
Thanks.
