Mine shut down once when I was deleting entries in Favorite. It also happened after I used SW 4.7 to download the new map. Apparently 4.7 has issue downloading maps and corrupting JVC file. It sometimes shut down my GPS when navigate to the JVC points.
Occasionally, my GPS unit will turn off without any reason. Is this problem experienced by other users?
Depends where and when., EG. mine once did it in the car whilst navigating the next time it did it I noticed that the power plug light had gone out and it was about to auto shut off thinking it had been disconnected for 30 seconds. I touched the powew plug in socket and it stayed on. (I must have missed it the first time DOH)
