I just finished installing a NEO Prolink PMZ3V9 in my Mazda CX-7 with BOSE. I didn't have NAV nor Satalite. I also sprung for the Blue Tooth integration and it works great. I use the Blue Tooth to stream the music while charging in my center console. I also discovered that if I connect my Ipod to the cable, turn my blackberry on to the blue tooth, I can listen to the music and if I get a call its a full car hands free kit. I really like it. I have added the link to the website I got it from. It took me about an hour to install (mostly running the cables took the time and it was the first time I took the center Stereo cover off).
