Hello! I have navigation Tomtom start 25. I have had it for two years! I decided to update my map through the official application from the computer, but unfortunately my map was deleted and I can no longer use the navigation in any way. originally the navigation is with a map of central europe and i am in eastern europe. I bought the second-hand navigation because I'm a poor boy and I don't have the money to buy a new one. in the application it initially appeared to me that I had two cards. of Central and Eastern Europe and now I only have a Central one that doesn't work for me. please tomtom help me to solve the problem.I kept my navigation a lot, even though I bought a second-hand one. help me use it again. I have no money for a new one!
