Dear All,
Does anyone have a clue how to make the GPS work again?

I know it is a very old device but still worked before the battery died. It is completely bricked, just generates some sound after powering on and that is it.

Any help in further steps are very much welcome.


PS. Garmin used to charge 150 USD for such a battery change, but for years this model is out of support and can not find any hint on how Garmin used to make it work in the past. There is CF Card reader in the device , maybe this can be used for the firmware upload?
