    BU-303 and SIrf

    Hi I have searched, but to no avail, this may sound ultra stupid as I don't yet fully understand the GPS thing, but.......

    How do I get Destinator to use my BU-303 in Sirf mode as I have heard it will update my position quicker etc....

    Do I need to switch its mode or anything?

    Many Thanks for putting up with what may be a stupid question

    Sorry just found it!!!!

    Yes it's quite simple.Download sirfdemo.exe (from places like www.holux.co.uk) and connect to you gps device using the normal NMEA settings, then once connected select from one of the menus 'Switch to SIRF mode' and close sirfdemo. Now reconnect using SIRF/38400 in d3 and it should work

    Do you have to do that every time you want to use it, or is it just a one time thing for the mouse itself?

    I havent had success with this....

    I connect to COM8 (the Prolific crap port - same as in destinator), then I put the baud at 4800 (same as d3 frontend), i go to "open source" thingy in the actions menu, (Otherwise the sirf mode option is greyed) then I get a bunch of data in the debug window, but nothing somes up in the other sirfdemo windows, then I select the "go to sirf mode" or whatever it is (it is no longer greyed), then I close go to d3, but it still only connect as NMEA/4800....

    I'm gonna try it again, but am I doing something wrong?\

    thnks!

    I managed to set it sirf mode using that program... just clicked on that 'change to sirf' option. Loaded Destinator 3 up and set the mode to sirf in the GPS settings and it found it ok.

    However the update rate didn't improve at all.. actually seemed to make it slower

    Is there any other way to make the Destinator 3 front end update faster as at the moment its about 30 ft behind my actual location when travelling above 30mph... gets a bit annoying when theres loads of streets and you have to work out which one you need.

    really? how many sats have you got a lock on to on average? I have about 4-5 on average and my gps receiver is on the roof so can't get a better location than that. Also its always loosing lock especially near built up areas which I was expecting but not as much as it is doing.

    Is Destinator much more accurate with sirf mode then?
