What exactly is SAT ready?

[SrMichi]

I just put in a kenwood hu On the golf and it says it's SAT ready. What exactly do I need to get for it to work?

[Drummer]

satelite radio ready, cant remember how much the box costs to hook it up to your radio but look it up and you should find it.

Is it something like HD radio box? If I get the box there is no need to buy a unit like the starmate?

SAT ready means that the head unit is satellite radio ready (XM/Sirrius). You'll need an XM/Sirrius tuner in order to receive the signal, and a cable to plug into the back of your head unit, and you'll be able to switch stations and view song and station info from your head unit.
