Hello Fabrice, thank you very much for your response. I've had some issues in synchronizing with QlandkarteGT. Maybe a corrupted database due to that ?? Database was deleted and everything is working now. Inclusive deleting the tracks. Thanks for your help and for porting Qlandkartem to N900. I'm using QlandkarteGT since a long time and selected the N900 mainly because of QlandkarteM. Christian
