In car Bluetooth kits, what installed audio?
 

I'm thinking about buying the CF30 kit from Motorola as it lets you connect two phones by Bluetooth at the same time. You can buy various audio cable kits for the CF30 to fit different cars and the guy selling the kits ask...

Does my Chrysler have:
- an amplified sound system?
- an Infinity sound system?

The answer is I have no idea... I have the 2005 Grand Voyager 2.8 Limited XS version, I know the sound system in it is meant to be better than standard but not sure how. Can anyone help me answer the above question?

Thanks.
