Congratulations!!! That will be a long drive. I made the trip from Dallas to Orlando a number of years ago. You can make a stop in New Orleans

You will probably be fine with the factory unit. When you go with the Pioneer, just put it in a safe dry place and you can put it back in when you go to sell down the road. I was actually fairly impressed with the factory system at least the little I listened to it. I don't think the Hummer dealer will install it. Are you buying the Pioneer from a local dealer or over the internet? If locally, they should be able to install it for you. Well, glad I got to drive one finally, but it is also a little depressing to know that it was mine if I wanted it and it is not sitting in my driveway right now

Oh well, I can wait a little longer I guess.
