Looking to upgrade the audio system in my 2012. Has anyone bought a head unit on amazon? The prices are so much cheaper than Australia.

Shipping isn't a problem.

I'm more concerned about the slight differences in model numbers between here and the US. I'm looking at a Pioneer AVH-X8550BT ($1200). The closest on amazon is AVH-8500BH (less than $500).

As far as I can tell the only difference is the region code on the DVD playback which isn't huge as I don't plan on watching movies in my car. Is there anything else I need to look out for though?
