Hi Is it possible to install the apps Waze or Sygic in the Gen 4 Prius, replacing the existing gps installed from origin?
Depends if you have the 2020 model which will have Apple CarPlay (and possibly Android Auto if they decide to do updates). With ACP you can mirror the phone's navigation onto the stereo screen so you can use your phone's navigation system. If you have an older Gen 4 then your only option is to buy an after market head unit with android auto/carplay so you can use a different nav system. Otherwise no, you cannot change the default system nor is there an update to do so.
