Do they put in the portable Sirius radio? I have the dock in the house, but need to get the car parts put in

Best Buy in general does, but this location has an autotech with a very limited schedule. Call ahead to see if you can schedule an appointment.

I don't know if they do it because I never asked

Yes Geek Squad

They install regular car stereos, so most likely.

Probably yes. If not you could use walmart, true value and or youtube

I would think so, call the store directly and speak with someone on the squad
