basically there are going to be the pioneer avic and the kenwoods.
i have the kenwood because of the garmin navigation that comes with it. it installed easily in my 06. it might have taken me 45 minutes. I got rid of my PIE adapter because I had just way too many items that I wanted to input in, which caused a huge cluster of wires that were dangling across my dash.
i suggest going into an electronics superstore and finding one that you like.
SUGGESTION: get an alarm. my first dvd player was yanked out. my second one has lasted a lot longer, which i owe to the alarm. I also bought a dummy face plate that covers it and makes it seem undesirable.
