Thread: Serious Problem with missing system file nuvi 2495LM Please HELP !

Hi guys,

Hi guys I have Garmin Nuvi 2495 LM and the following problem.

A friend of mine tried to install a map and after copying the gmapsupp he maybe deleted something i don't know, but : THE DEVICE does not want to start up. No access to the memory card at all. After starting...
It starts with Garmin Logo, Says Loading Maps.... and then reboots when connected to cable or shut down when not connected to cable. I have no way to boot the device or to access the internal memory ?
I have tried to hold the left corner top and enter into some screen calibration mode. Afterwards i was able to see the device in Webupdater and then the device disappeared again. I have tried using Webupdater to fix the device but it didn't detect it. After I enter in calibration mode by pressing top left the webupdater detects the device but the screen shuts down after a while and i am unable to proceed with update. What to do ? Is there any way to update the firmware from SD Card ? I guess that it hangs on loading maps reading the internal memory and will not go to loading maps from SD card at all....
