Kona Blue! Nice choice!
I got the base model, too. The only thing I missed was satellite radio.
For now I'm using a Pioneer Inno portable XM radio.
Picks up a signal pretty good in the car, lets me record off air, and I can take it into work with me.
I have it mounted in a holder stuck in the center passenger air vent.
I just don't like having the wire running down to the center console to get to the aux in jack. Messy.
Works for now. Maybe in the future I'll consider the Sirius install.
