I've an 04 Subaru Legacy that I'm looking to install one of these hands free devices for phone calls. Never needed one before, but after driving my brothers 520 that had one of the Parrot systems (CK3100), I now feel lost without one. Is Parrot the only brand worth getting, or are there other ones available on the market. I will admit, I know nothing about car accessories and what's available, but I do know I want one that interupts the car stereo on calls and one with a good mic so that the person on the other end can hear me clearly. Also, do you need a fitting kit for these or have you to splice the loom in the head unit to get them working properly?
