When updating your 730N RHR Nav/Radio with the latest Gracenote v.5411 Do not use the USB Drive. Burn a DVD
Reports are coming in that updating via the USB port will BRICK the RHR unit.

Updating the unit with a new firmware still can be performed via the USB port (latest v.2.184)

 

Turning off the car during an update can also brick the unit.

 

Ijust looked online and checked the vin and there is no new update for mine.I wish there was nav is so slow taking input.I.use my phone instead.
