Toys for a Trailblazer-Christmas List 2005?

I just bought a Trailblazer and I have read a few posts on add on items. The post on Back up lights (item #2 on my list) was good now I would like to see if anyone has something neat that I could add to my Christmas list ie. GPS, wireless FM transmitters for DVD, portable DVD players things that fit in the Trailblazer. I am looking for proven things that work and fit in a Trailblazer with minor or no modifications required, I almost bought a 15" Toshiba DVD player, but it did not fit in the back seat.

I have found one toy, a Customized Lasercut Trailer Hitch Covers www.pcustom.com , this seller makes the trailer hitch cover to what ever design you want, he also has some pre-made ones.

I am on a strict Toy diet until Christmas, but it does not hurt to window shop.

The next few things I need.
