Since today I have excactly the same problem. (I haven't done anything abnormal) My player always thinks it's at home power, even if it's in the car. I found out that the problem is definitly not the power connector, since I checked it with an ohmmeter. (I divided my player into pieces) The contact in the power connector is intact.

There must be another (hardware) failure. All the other functions are working as excpected without any problem. I tried to install the old 1.03 software version, but the problem is still the same. Is there anything I can do?

Since my warranty is over since 2 months, I hope to get a solution without to ship my player to the UK.

Thanks for any help
