Aftermarket Navigation systems

[SunPilot]

I did some searching and I cannot find definitive answers to my questions. I hope this isn't a redundant thread...if so, I apologize.

I am the proud owner of a 2010 Trail. It does not have the Nav system...mostly due to a $4000 option price here in NY. I do like the radio with XM, but I need nav...I am used to it from my other car and I am moving to Arizona where it will come in handy. I am thinking about getting one of the following units:
Pioneer AVIC-Z120BT , Pioneer AVIC-X920BT, Kenwood Excelon DNX9960,

here are my questions:

1...Will the already installed XM radio antenna work with any of these units or do I need to use that unsightly mag mount unit?

2...I know steering wheel control will work for radio...will the Blue-tooth buttons also work?

3...Will the stock back up camera plug in?

4...What about the USB in glove compartment? I could probably rig a cable for this one.

5...Will I be able to use the already installed mic for blue-tooth?

I appreciate any help. If there are any suggestions on which units are the best, or installation opinions, I would love to hear them...Any info is greatly appreciated

At 13 pages, this thread will take a while to wade through, but it covers most of what you want to know: http://www.toyota-4runner.org/5th-gen-t4rs/61082-aftermarket-stereo.html
