GPS Hardware/firmware problem ???

[vcp]

After 2 days trying to make tomtom get a fix with me new (bougth used) Trinity without success, I installed GpsInfo to try to understand what was gps sending torough its comunicactions chanel (NMEA/COM9/4800), and found following:

It seems that NMEA sentences are sent 'without data', something like :
$GPGGA,,,,,,,,0,,,,,,*66
$GPRMC,,V,,,,,,,,,,N*53
$GPGSA,A,1,,,,,,,,,,,,,,,,*32
$GPGSV,1,1,00*79

On other pda, between every comma, there is a data/number, that I assume is the info thata the gps is sending....

For me it seems that gps has lost it´s configuration and is not able to send NMEA data, but it is working because I receive NMEA Start/End heads.
Is this assumption correct ???

If so anyone knows If gps chip(s) can be diagnosticated/reconfigured/reprogramated ??

P.S. It was bought with WM5 and Radio 1.38.
I've insttaled Radio 1.50 and WM 6.140 (Niax) and sympthoms are the same.

Any hint ???
Thanks

sorry i dont know the technical aspects of your question as far as reprogramming the gps but i do know that unless i have the following selected i dont get gps in any programs:

settings -> systems -> external gps ->

programs
gps program port : com2

hardware
hardware : com9
baud : 115200

access
manage gps automatically (yes, checked)

you might already have done this but i wanted to cover the first step before you go then, tell tomtom to look in com port 2. i also bought a used trinity with wm5 and no gps but those settings was all it took and now it works. good luck!

Trying to reproduce your config, tomtom says 'No Gps available'.
I assume you are configyring 'another NMEA GPS' and com2.
What velocity have you selected in tomtom?

i think a have the problem ... its possible to navigate with tt but in the tt gps settings everytime he says no gps device but there is a connection. shown to me by the coordinates and like i said its possible to navigate. if i set up the gps new in tt there he detects the nmea gps successful but only 4 maybe 2 seconds. then its again no gps device ... sry 4 bad englisch ... any solution?


edit: well tt show me flight mode all time ... !
