I'll respond to your questions shortly.
Had a 1000+ km trip today, so could extenisvely test this tool/gadget. Approved.
Here's a picture (+ close-up) that gives you a good idea of it. Very comfortable and relaxing to (physically) read the data at whatever time of day/night, also when you wear sun glasses (compare with the difficulty in reading the small black text shown inside the grey SATNAV screen blocks when wearing sun glasses). You can also adjust the brightness or leave it on automatic brightness (adapting to the environment darkness/light). I'll add both pictures to the first post of this thread.
My 1M engine is 100% stock (no tuning). Highest torque and power figures shown so far on the head-up screen: 551 Nm and 266 kW (362 hp [metric]). That's quite a bit more than the official figures (450+50 Nm and 250 kW (340 hp [metric]).
