I am trying to update an old GO 300.
The current Navcore is 5.201 and Great Britain Map V562.
As you can tell, it hasn't been updated since purchase quite a few years ago.
I have updated the Navcore using TomTom Home to 7.903. However, I cannot update the map. I have looked at the compatibility charts and have tried both of the following maps for the UK and ROI - 860.3101 and 860.3126. Both should be compatible with Navcore 7.903 and GO300.
After using easyusetools or Alberts Easy Activator, to activate the map and to patch the TTsystem file, I get No Map Found error on the device. I have tried for a while with different combinations of maps and activation tool and cannot get it to go. I even tried Navcore 8.562, again without success.
I have also noticed that in the original map folder, there is the older Great_Britain.mid type file for the activation code. Is this relevant?
Can anyone please help me.
Try SE Navcore 8.142 it runs OK on the 300, its already patched and ready to use.
Then get the 860.3101 map and patch that
