How tu UpDate Maps in the New 2012 Nuvi Series (34XX, 24XX, 25XX)
The new 2012 models are MTP Devices. That is why when you conect them to your PC they are listed in Other devices in My Computer. And it doen´t show the System Folder and are not recognice by Mapsource. What we have to do is, in the GPS go to Volumen, then hold the upper right corner a few seconds and it will show a hidden menu. Go to MTP Setting and choose Mass Storage or Mass Storge Single Session. Conecte the GPS to computer and now it shows up in My Computer as a removable disk and everything is accesible as usual. Including useing it in Mapsource.
