Hi!

I'm trying to get an old Tom Tom One to work following the gps wnro problem and despite using the 9.541 software, the unit will not display time or lock!

Can anyone advise me:–

Which particular GPS Receiver chip is affected;

Is it possible to exchange this? i believe Tom Tom Ones used several types of these devices on their boards, which type of chip do I need and can anyone post clear pictures of non–updatable chips that don't work, and updatable ones that do please?

I don't mind buying another TomTom One m/b if any Member can confirm which type is OK!

Hi!

I've already installed the 9.541 Navcore that is supposed to correct the issue, along with the glgps.dat  in the."bin" folder of the TomTom that's supposed to correct the issue but it's making no difference – the TomTom's time is till jumping back to "0:00" after finding two satellites, and it's taking over 15 minutes to get a lock

I believe this is more a firmware issue, rather than a chip hardware one. If you have copied the files, I read you may need to reset the device though the pinhole it the bottom 3 times. It may need to hard reset to accept the new files. Also someone else mentioned about an ASR folder causing problems (freezing). So maybe check if you had copied that, and if you had, retry without it.
