Options for playing audio from my tablet through the AUX input

Hello,
Bought a O5 Tacoma over the weekend and looking to do some upgrades.

I current have the stock radio nut sure if is mutli disk or even if will read MP3 disks. I just want to able to play stuff from my tablet through an AUX input. I found this Car Radio MP3 Player USB AUX IN Adapter For Toyota Camry Corolla Highlander and says it will work. So I am trying to decide if I should order it or look for a touch screen aftermarket with bluetooth that I could then add a back up camera to.

Any input is appreciated.

 

I am on the fence sometimes I want the back up camera for the times hooking up a trailer or tight parking lot and but I start looking the price of monitor and camera and I am shocked. I tested drove a 2010 with the monitor in the mirror and still found myself using the mirrors to back up. Plus had no proximity lines so really not a lot of help. Maybe the the plug in and when the radio dies then go touch screen.
