Hi everyone,

I’m stuck with a Garmin GPSMAP 620 that’s showing the dreaded “Software Missing” screen. Neither Garmin Express nor WebUpdater recognize the device, but I can get it into boot block mode.

I’m desperately looking for the GPSMAP6x0_WebUpdater__320.gcd file or a converted .rgn version to flash and bring it back to life.

The original Garmin download link is dead, and I haven’t been able to find any working mirrors.

If anyone here has a copy or knows where I can get it, please share it — it would save my device and my sanity!

Thanks in advance for any help. Really appreciate it!
