I just got off the phone with a rep at NEO (The manufacturer) and he says that this unit (
product link ) will work with the Mazda CX-7 NAV-Unit stereo utilizing the SAT port. You must disconnect the Sirius connection.
He claims that you get full-control of the iPod interface unlike the Mazda on (and others) that lock you out, you get use of steering-wheel controls to skip or go-back a track, he even said that it has the ability to connect to an iPhone (my current means of music transport). He also said that "some" information will display - but he wasn't clear WHERE... I doubt it's on-screen... my guess would be the monochromatic digital dash readout.
Anyhow. His final assurance after I belabored my concerns with numerous questions was; "At the worst case, if it doesn't work for you, you can return it for a full refund."
So - I cannot vouch for any credibility to his claims, but I do not see why they would lie about it. It would *appear* that this could/should work. I don't give a rat's-ass if it displays anything... as long as I have a reliable, PHYSICAL connection from my device to the input of the audio system, I am a happy man.
If anyone beats me to the purchase and insatlls it, let me (us) know "how" you actually interface with it and how it interacts with the head-unit (display, functionality, etc...)
Thanks.
