We've got two Moto phones,a V3 and an L7.
Both work perfectly and charge through the normal charger and a computer usb connection.
I also have two car charging leads,each one has a little red light which shows me its correctly plugged into the power outlet in both our cars,however neither lead seems to charge either of the phones,the phones themselves dont register any charging activity.One of these leads is brand new too,only bought after I thought the problem may be with the first lead.

Is this a common thing?, is there perhaps a setting on the phone(unlikely I know) that needs activated?

Does anyone else have the same problems?
