I have a 2010 Mazda CX-9.

My Nav/Entertainment system was "clicking" (appeared to be having trouble reading the DVD) and Nav was not working.
Other functions were working (e.g., Touch-screen radio controls, back-up camera, etc.)

Based advice found on the internet, I attempted to clear the Nav system issue by disconnecting the battery. Now, the Nav/entertainment system is displaying this error message: "A Program Cannot Be Read . Please Consult to a dealer" (radio works but screen is displaying error message - so, obviously no touch screen controls, no back-up camera, etc.) Also - when I try to insert the DVD (I'm assuming the program it wants is on the DVD), it clicks a few times and spits the disk back out.

Notes:
The Nav DVD is fairly scratched. I tried it in two PCs - and one PC could not read it (the 2nd PC could read it).
In the PC that could read it, I made a copy and tried that in the Nav system - but got the same result (clicks a few times and spits the disk back out)

So - here are my questions:Any guess on the likelihood that buying a replacement DVD will resolve the issue (I'm guessing not, since the copy didn't work - but perhaps there is a disk formatting issue in the copy I made)?

Is there any other way (other than the DVD) to get the Entertainment system back up and running (If I can live without Nav)?I see various "replacement units" on the internet - and the job of swapping out doesn't seem that difficult - but I'm wondering if the models are really "plug-and play" - or if I'll have other issues with a replacement (considering that it integrates with back-up camera, etc.).

Thanks for your help!

 

did you ever fix this? I have the same exact issue

 

Same issue

 

You're screwed. The DVD unit is no longer functioning. And the DVD unit controls everything. Either get it replaced or have an aftermarket unit installed. A really lousy design by Mazda IMO

 

Unfortunately, it wasn't designed by Mazda.
