Can the Garmin 520 be charged while riding? I am looking to buy the Garmin 520 for some brevets but it only makes sense to do so if I can charge the device while riding. Does anyone know if this is possible? 

I know that the usb port is in a funny place on the back of the device which will make charging difficult, but I just need to know if it is possible or if it will go into standby mode during charging. 

I know that some models allow for charging while riding while others do not. I want to know if this model in particular does. 

Thanks!
This thread contains all the information you would ever want to know about the Edge 520.  The bottom of Post #67 says that this is indeed possible.
