Hello Guys!

I have a 2008 Mazda CX9, came with the OEM 6 disc CD Player that has no touch screen.
I saw on ebay the OEM CX9 radios for sale with touch screen and decided I would buy one.
I have a factory backup camera installed on the car (seems like they all come with one?), so I figured it would switch out the radios and be able to connect the back up camera but I had no luck.

Right now the touchscreen radio works fine but:
No backup camera
No GPS

I am wondering if anyone has done this upgrade and was able to get the backup camera connected and maybe even get the GPS working as well.
Thanks.
