Is 9.541 still the best Navcore for Sirf3 TomTom

A NC 9.541 isn't recommended for a ONE device. Especially not for a device with SirfStar III. Too sluggish and the biggest nonsense for all devices with updated SirfStar III gps-firmware (also all Gox20/30/7000).

This is a NC with WNRO-fix for ONE-devices with GL1 gps-chip. For use with your SirfStar III-device you must delete the folder "fixdate", the file "ttconv" in the folder "bin" and the files "ttn" and "suicide.dat" in the main directory. Make a backup of your ONE, delete all folders and files without your map-folders, voice-folders and your ttgo.bif and copy the extracted content of the NC-archive to your ONE.

This TomTom is 4N00.003, and come up in it's bif as TomTom One V2. Anyway, it has a Sirf3 GPS chip and I have flashed the GPS firmware to 3.6.0. I think the satellite fix is better. It certainly is no worse, but sometimes still seems to take a while. Now that the GPS chip is re-flashed, is it advisable to stick with 9,541, or go back to what I was using before (9.170) or 9.510 perhaps. Since I stared using 9.541 startup Rating: 5
