A few days ago, I finally get a new 1410 with this known problem.
Symptoms:
The device can not be flashed with the correct firmware - after "Loader loading" just appears "System Software missing". Also, device can not be flashed from SD card. Erasing the memory with the command ergn not work.
Reason:
The main memory chip physically cannot recording.
Solution:
Just replace the memory chips on the same from Nuvi 205/205w/500/1200/1300/1400.
