WOW...just upgraded to the 737-800/900

Didn't know that there was such a huge diffrence from the PMDG 737 600-700 to the 800-900 :o
Anywasy
What is the point of Acars I saw them use it in a video once were the pilot reported the weather by putting it in the ACARS but othere than something to look at why is it their
Also how do I turn that funky panel to the ordianry one that came with the 737-600/700 (please say you can take that off)
And last how do I get TCAS to show up?
Thanks
