Hey guys, have a few questions about the RCD310 unit which comes standard with the 2011 Polo GTI (apologies for the nooby questions):

1. If I ordered a GTI with no options (except metalic paint), will I still get the audio
buttons on the steering wheel (for the RCD310)?

2. It is my understanding you connect an ipod via the AUX feature? I haven't been able
to find any information, pictures, etc on the aux such as what are the limitations and
the disadvantages of this?

3. Do I really need MDI?

Thanks,
Am kicking myself for not getting the RCD510 option. Would have been worth it for $500, although some ppl have been saying it cost then $770? confused :S
