Thread: Garmin Map 62s "System Software Missing"

At it's most serious, the message "System Software Missing" can indicate physical flash damage involving the region containing the firmware [Garmin calls it 'system software']. Mostly it's less insidious and only means data in the firmware region [rgn14] has become corrupt or has been erased in which case that's easily fixed by reflashing.

The error message you've got from Updater.exe is concerning if you've tried multiple times to flash and have used different USB cables, different USB ports or even another PC. Note: Use only directly connected [no hub] rear USB2 ports of the PC, not USB3.

If you've tried all the above then please post a link to the firmware you're using, maybe we can try something else.

Thank you,
I didn't have any luck loading files onto the unit but found that if I squeezed it while turning it on it loaded normally.
I opened it up to check if something was loose, looked fine. It then started like it should and ran for a few minutes before shutting down to "System Software Missing" Message again. I managed to do an update using Garmin web-updater, the update loaded but the unit still shut down after some time.
Will have a bit more of a play with it soon but thinking its most likely caused by physical damage.

To get the RGN file do I create it by running the Map62s latest GCD update through a RGN tool? Or is there a RGN file available somewhere to download? Just want to make sure I'm actually doing it properly.
