Hi I have tried to install this v5.51 beta firmware manually by dragging the GUPDATE.gcd file into the Garmin folder and then unplugging the device. When I do the latter, nothing happens.
My issue now is that the 830 is plenty buggy on v5.2 and I am not able to get any OTA updates by going to the About section of the device menu. It's stuck on v5.2.
Can anyone advise what I should do please?
The unit is a local Singapore authorised distributor set if that matters.
Thanks
Lucas
