mazda 3 and harman kardon drive and play
 

I was wondering if anyone has had experience with Harman Kardon's new Drive and Play. It's an integration for an iPod using a separate display and input handle. It looks pretty cool but I don't know if the M3 has an audio input on the rear of the head unit - otherwise you have to use a FM transmitter. The cost is around $200US plus installation. I wondered if it were worth the effort and money.
