New to the forum and new owner of a brilliant black 2012 Mazda 5 Sport. I just replaced the stock stereo with the Pioneer AVH - P3000BT with the Scosche MA1548B single/double din dash kit. I also installed the MicroBypass so I can run some apps while driving, without it you can only run some things like the DVD player while the car is in park and the parking brake is up.

I'm completely happy with how it all turned out, it looks stock. Pics attached.

 

DUDE!!!
Thanks for posting. I was wondering what a setup would look like. My Q's are these: Do the steering controls still work? What about bluetooth thru the car? Phone?
Thanks again!

 

@Jeff M.
Thank you for posting this, exactly what i am looking to do with my '12 M5. Where did you get the Scosche MA1548b? I tried Crutchfield for the Metra kit but they do not stock anything for the '12 yet.
Steering wheel adapter?
Thanks.

Update, found the scosche online for 28$ free shipping. Now to find wiring harness for steering wheel controls (if it even exists)
