I too like the auto belts. I don't understand the hate for them, TBH.
As for Sirius/XM radio... i had that for free in the Veloster for like six months. Every time i turned to the few stations i sort of liked, it wouldn't be long before i heard something i didn't care for, and rarely did i hear something new and think "Hey, this is great. I should look this up later." I've resorted to finding most of the music i like on Youtube and following up from there to obtain it and put it on some form of portable media.
