It is on the car. I saw mine sitting in a holding area at Flat Rock. A few days later it was at the rail yard, then I could see it on the rail car heading my way, and finally at El Mirage here in Phoenix before getting on a car transporter heading to my dealer.
I did try it today, and it cycles through the presets like the other poster said. What I did was set up my 4 favorite XM channels in a row, and then I can jump between them from the steering wheel. The screen changes within a second or so.
A faster charger can always go slow, but a slow charger cannot go faster. It all depends on your needs and expectations. Instead of taking 5 days to charge, it takes one.
I would most definitely put a battery charger on it when you bring it home. The battery charge is usually pretty low at delivery unless your dealer charges it for you... probably uncommon.
As for a battery tender, it's a good idea if you don't drive it very far. Please note that the Gen7...
