Hi Rob,

I don't have any experience of that particular GPS, but most SiRF-based receivers still default to the NMEA interface protocol.

You're very unlikely to be able to flash the firmware, but if it can switch between NMEA and SiRF protocols, it should "remember" which it was using over a power-down (unless the internal battery has failed, which would also produce very slow acquisition times ~5 minutes or more).

Are you sure that winfast is switching the protocol, or might it be setting the interface on the PDA in some other way? What PDA and other software are you using?

If you want to look into the depths of SiRF, then you'll find more than you can possibly want to know on the GpsPasSion website.

Cheers, Alan.

hi Alan,

Many thanks for the reply and apologies for my late response!

Its a medion ppc250 PDA so nothing fancy and im using tomtom 6

the only way i can get tomtom to work with this gps reciever is if i use winfast and then select nmea etc etc but i then have to close winfast for tomtom to see the gps reciever - as you can imagine it is a long winded process!

I have no idea if winfast is actually switching the protocol - i just assumed it was!

The gps worked fine back in the day of tomtom 3 when tomtom operated or had the option of sirf

If i read your reply properly you say that the reciever has an internal battery???

Hi Rob,

I can't find a detailed specification of either device, but this seems to imply the default should be NMEA. It doesn't even mention SiRF, but I suspect it is SiRF2, like my RBT1000.

To get reasonable acquistion times, GPS devices need to have data about the currently-visible satellites. So yes, nearly all GPSs have an internal "button" or "coin" cell to run a Real Time Clock, and to store data (which should include SiRF/NMEA protocol status, where appropriate).

There are several ways to proceed. Personally, I would install SirfTech which will find the current protocol and allow you to change it. It's not very intuitive to use at first, but IMHO it's safer to use than SirfDemo or SirfDemoPPC applications on PC/PPC (but don't change any parameters that you don't fully understand!).

Alternatively, try the "TomTom Driver" linked by mikealder in this thread. Note that it's not a normal driver, but a fully-fledged independent application. You could also try APLSirf refrerred to in the same thread, but I've not used that.

Cheers, Alan.
