Any help would be much appreciated, I'm new to this forum.

I'm looking at used A3's to buy, and I noticed the button on the righthand side (for bluetooth) has a different picture on it in some A3's.

Some have a button with a picture of a face in profile on it, like this:

and some have an arrow, like this:

Does this difference have a significance? Will on versions work with my bluetooth phone and the other won't?

Also any other advice for someone shopping for an used A3 is much appreciated.

 

I bought an A3 and the bluetooth works on it. Here's what I found for anyone with the same question:
I'm still not sure why there are different icons, but it is probably related to the year of the car. I bought one that has the arrow icon on the steering wheel, and the bluetooth works in this car, but I have driven another A3 with the same arrow icon and bluetooth didn't work, so the icon is meaningless. It seems that if the A3 has the connector in the center console armrest for a phone cradle then bluetooth will work, if it doesn't it won't. At least that's what I've gathered.
