new radio

I was looking on crutchfield and found this radio for my vx. Since I have a 3g usb card this is almost to sweet to pass up.

Will this fit a VX, simply?

How much for the monthly wireless data phone plan?$$$$$$
Seems just like clipping your iPhone to your dash.
At least the phone can travel from car to car to walking.....
Don't get me wrong, I think it's pretty cool. I'm just cheap when it comes to signing up for a monthly $Bill$.
$100.+ a month, buys a lot of $4.00 a gallon gas.

I have a plan with verizon and have unlimited usage for $29. But that has since changed for new accounts.
