yes. you can have an extra SIM, yes you can download off-line maps.

pero iniisip ko lang yung benefits nung may separate GPS ako compared sa ngayon na CarPlay na lang gamit ko.

naalala ko din na yung GPS ko noon will show you a photo of the intersection and tell you which road to take

anyway, past is past... just like the CD player, lahat tayo may CarPlay na and the GPS had to go.
