Mazda 3 Fastback 2019 – Infotainment and general questions

Hello, I’m interested in buying a Mazda 3 Fastback. At the moment I’m still swarming strongly between the Mazda 3 and the new Seat Leon. What I like about the Mazda is the design. Especially the Fastback very pretty. Which convinces me less compared to the Seat Leon is the infotainment system. The touchscreen and the connection of Android car seems to me to be better at the Seat. If you already have a Mazda I would have the following questions: 1. How do you like the car allg emein? 2. Does the infotainment system actually have DAB or DAB+? Because the documents always only talk about DAB. The plus is not mentioned. 3. How does the operation of Android Auto / Apple Car without touch work? Can you just use it, or is it difficult to switch between the apps. 4. Can you use the functions of Mazda and Android at the same time? So can I use the Navi from Mazda and play music from Spotify at the same time? Or the other way around Goo use gle Maps and listen to music on the radio at the same time? Thank you in advance!
