Nuovo Garmin Zumo 660 - New 3D

Ecco le prime due risposte
a)Make sure you are getting power. See if it works in the car cradle and when all else fails do a Master Reset
b)Many times just holding the power button in for 8 seconds resets that problem for me.
In pratica mi sembra di capire che entrambi consigliano di resettare
