Gps/bt/xm Question

[deathwish]

I purchased a 2009 Silverado 1LT in July. I have been looking to put an in dash GPS/DVD/CD but I have found out I am going to have to install a mic in my cab, an antenna for the GPS and another antenna for my current XM subscription.

 

Is there any head units with GPS, BT, and XM where everything is self contained like the current OEM setup? I apologize if my question is confusing, if you need any clarification ask.

 

Thanks for the help.
