Question about Garmin DriveSmart 65 Full EU MT-D

1. is it possible to plan routes with this device, e.g. on a PC, and then transfer them (Wifi, BT, USB?) to the navigation system? 2. additional question on the report by GelegentlicherKaeufer: Are there any other experiences among the readers here regarding the live traffic update via DAB+? If it really doesn't work in the greater Zurich area, I'm missing a weighty, if not the weightiest, argument for buying this device. Since TomTom only offers this function by linking it to a smartphone, Garmin would be the real alternative. But only if it actually works. Does anyone know more about this? Since I don't have DAB+ reception at home either (because of "better coverage than FM"...) I'm questioning the DAB+ story in general, and even more so right now.
