Hi 6 months ago my built in Tom tom sat nav in the car froze when i started my journey. I restarted my car and it said that no maps were found. I installed Tom Tom Home and updated the maps but it it did not resolve the issue. After a number of months I have come back to try and fix this error again. Now I have an additional issue. When opening the Tomtom Home it tries to install a critical update I have left this to run for over an hour. The download bar looks complete but the update doesn't progress. I have reinstall Tomtom Home but still face the same issue.
