One day this week I was enjoying my XM radio Christmas music station.
The next day the free subscription for my rental car had expired. SO SAD!

I love when I get a rental car that has:
XM Radio
Cruise Control
Bluetooth

This week I looked in several different cars trying to find BlueTooth. I thought I was successful but it ended up just being OnStar. So I broke down and bought an after market blue tooth device and am quite happy with it. It is just so much safer to drive with this.
