Need some help with GL questions...

[2thdr]

Making the switch over to MB from BMW for the next SUV. Ordered a 2010 GL 350 on the weekend and have a few questions:

i) are the 2010 rear entertainment system's monitors TFT-based LCD's or LED-based?

ii) can the 21" AMG wheels fit on a non-550 body without extending too far beyond the fender flares? If not, what is the final word on putting the fender flares on the GL 350?

That's it for now. BTW, tried searches but not coming across much in the way of definitive info.

Thanks in advance for any and all help.
