Yes,I ran the Ovi maps without the phone connected to the pc and I ran it also when the phone was connected to the pc.I don't know why,but the problem sounds to me like a data loss.So,I suppose I have to flash again my device?

P.S.oes the gps on n900 work offline?I would like to go somewhere with my car and I don't know where is it.Also,I don't have an Internet connection on my n900.So,is there any way to use the Ovi maps while I drive
