Do Orlando Car Rentals Come with GPS?

Next week, I’m taking my family to Orlando for 2 weeks. Not only are we going to visit Disney World, but we’re also going to drive around to see some other sites in the area. Of course, we’re going to have to get an Orlando car rental. My question is this: do the rental cars in Orlando come with a GPS system?

We’re going to be doing a lot of driving around in unfamiliar areas, so I don’t want to get lost. If I have a GPS in my Orlando rental cars, I’ll be a lot more comfortable driving around the city. The last thing I want to do is get lost and have to pull over in a strange area to ask for directions.
Plus, I’ve always wanted to give a GPS system a test run. I’ve been thinking about buying one for a few years, but I never wanted to drop a couple hundred dollars without testing it out first. So, this could be the perfect opportunity to see if it’s worth the money.

So, do you know if the rental cars these days come stocked with a GPS? If you know, please tell me in the replies.
