Customer Question

(2010 Mazda CX-9 Grand Touring AWD, Bose sound, in-dash DVD navigation system, rear flip down DVD system, backup camera, Bluetooth hands free) The dvd navigation system appears to have stopped working. Instead of replacing the system for the painful price tag of $4000-$6000, can I buy an aftermarket system for $500-$600 and have everything still work?

If I were to buy a used factory unit from the website you mentioned, would I need to pay to get anything re-programmed or will everything work just from the initial hookup?

My info isn't showing that it needs programmed but sometimes it doesn't list all the modules that need programmed.The only way to find out is call a dealer and ask them to be sure or install it and see if it operates without any programming.

Thanks Pete
