Hi every one. Im Ciro and I picked up my loaded silver Passion about 2 weeks ago. I love the car a little more every day that goes by. I am a little curious about a couple of things. First, the radio. I did pay $350.00 for the premium system that should have the six cd changer and 2 tweeter, 2 mid Range and sub woofer. How do I know if this is the radio that is actually in my car? Are these extra tweeters and subwoofer visible? I do see two speakers on the door but thats it I have not tried the cd player yet but will soon. I could be wrong but it seems to me that every grade of radio in the smart cars look the same. Second Question about the alarm. Is there a way to test it while it is activated to see if it is working? Thanks in advance for any responses and I hope all of you enjoy driving your smart as much as I do.
