Metra 99-7627HG

After year of contemplation and research I finally decided to give this device a try. I really wanted to upgrade my Pathfinder's stereo, but being that this was the only option to do so I was hesitant because I was only able to find 1 or two reviews, and both were negative.
So I got the 7627HG and paired it with the Pioneer 2300NEX. The kit does pretty much everything it is supposed to do, outside of a minor rear AC issue, and the factory backup camera not coming in. I have not updated the software yet, so I will see if these things are corrected before I contact support.
