While in the car and i have the FM Xmitter on if i connect the in car charger it tells me that i cannot run the Xmitter while a usb device is connected....

WHY !!!!

Thats daft... long journey i need to charge and i want to use the device to play mp3s / videos in the car and then i can't charge the device while doing it - makes problems for me.

Any work around to this ?
