Since WRNO happened I have been using Navcore 9.541 on my TomTom 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 is quite slow, the power on screen stays for 30 seconds or so before it goes to the navigation screen, Previous Navcores were always much quicker. Alternatively, is there any way of reducing this dead time on 9.541, and what the heck is the TT doing during this time? As far as I can see, the only practical benefit of 9.541 now is that suicide works (though now I have flashed the GPS chip I seem to no loner need it).
What Navcores are others using on these old 32 Meg RAM Sirf3 TomToms, and how are you getting on with them?

By the way I has a short trial with computer voices but have gone back to the original as the TomTom seemed to be quite slow and speaking.
