Update to MAG 420

[St Martins43]

I currently have a Mag 254 which is a bit temperamental on booting up. I am considering a 420 to replace it but understand you cannot load a URL direct onto these newer models. I note this is still Linex software and not Android as the latest unit is.. Can a URL be loaded directly onto this model. I can manage the basics but don't want to buy a nit which I cannot use
