I was wanting to ask the forum if anyone has replaced their radio with an aftermarket?

I currently have a limited edition which has a nav and xm. All factory of course but I was thinking about upgrading to an Alpine or something. Any ideas and photos out there of what an aftermarket looks like?
I also want my steering wheel controls to work. Can that work in the aftermarket radios?
I am wanting to see some photos to see what it looks like. I have never seen an H2 with an aftermarket sound system

You already have a nice factory set up but ,I just sold my H3 that had a Kenwood dnx6000 model stereo with bluetooth and navigation by garmin. It was by far the best radio I have ever had. Its a bit pricey but I thought it had excellent sound quality. It also played dvds while driving if you tip the install guy not to connect the parking brake safety switch thing. I wish I had not sold it with the truck. Just check out Kenwoods website and look at their navigation models.
