Thread: Navcore v9.541 SE for One/XL 32MB by Tonyzeta

I have updated my TT ONE 2nd edition with the new bootloader 5.5120 and navcore 9.541TZ, and the
United_Kingdom_and_Republic_of_Ireland_1030_9519 map.

Thanks to this thread it all went very smoothly(except for the above glitch)...so thank you so much everyone. Its nice to keep the old TT ONE running for a little bit longer.

I have yet to try the TT out for real, so I dont know if it has fixed the GPS Week Number Rollover problem that my satnav was having. (Would lose the signal occasionally and sometimes had big problems locking on to the satellites).

However I did try it outside for a few mins and the time did look to still have a problem still. I will try it out over the next week. I am not to too bothered about the incorrect arrival time, but would like the satnav to work better with the satellites then it did.
Thanks again.

A further update. Because the above did not fix the time problem, I checked the GPS chipset for my device. I had read that it used the SirfStar III GPS chipset. However today I discovered (by holding down the on button whilst turning on) that my satnav uses the GL1 chipset.

So I then used the ttconv download in the thread "WNRO GL1 Clock Error/Sat Fixes Workaround" and my TT ONE now displays the correct time and I think is latching onto satellites much quicker. I think that I have got there in then end thanks to all your help.
