Finally got around to purchasing and installing the same Belkin AirConnect module and I love it, works well although the calls are just a bit muffled. Overall, can't beat it for the money. Sent my radio out to have the aux-in installed since there are no DIY for Nakamichi head units. Cost me about $70. Then I just recently bought this Belkin unit and so far, it has been working well. Took a bit of time to figure out how I wanted to place everything. But I think it looks integrated enough with where I finally put it.
