Hi, I have 2008 Mazda Cx-9 with Bose Audio system. I want to confirm if I loose any functionality like clock setting, MPG display or handsfree blue tooth with RP4-mz11? I need to know this before I buy it from you

Best Answer: Hello,

These threads are meant for product questions, and are submitted to customers that have the product. So we apologize ahead of time if you get answers from customers who are awkwardly responding to your "but it from you" question. =]

The description touches all your points, except the bluetooth.
"Allows the clock to be set without having to plug in the OE radio"
"Information on the OE LCD can be changed to MPG"

Surely your aftermarket headunit has bluetooth, so It will take over that feature/functionality. Still, we suggest speaking to tech support, to ease your concerns.
