I did tons of research and I ended up with the Nav tv barracuda and isimple. I also enabled my radio have aux tab since I did not have RSE dealer can program radio to do this its called u42, you will need the multimedia kit which is 49$. This gives you av in and out with RCAs. Now I have a 3.5mm for guests using aux tab, the isimple for my usb drive and Bluetooth phone and audio. I also wanted Nav traffic which only came out in 2009 so I had to swap my radio with oemautopartsco.co and get a xm receiver from a 2010. I dont like the radio from 2012-2014. I like the one from 2009 because I still have tilt and 6 cd/dvd changer. Also when I get a bluetooth call I can answer from steering wheel and radio shows caller ID. When I play a dvd upfront my headrests shows the same so the 6,DVD changer comes in handy. I am now going to get a module that shows my iphone screen on my radio. It goes for 90$ I put a pinhole camera which I sell at spy shops in the front so when I press the up mirror it shows the front and down shows the rear cam. This happens when left or right control is in the middle. Barracuda is the winner , it also haves a lot of other options like 12v controls to customize. I could not be happier. I have a iPhone 6 and when I use pandora or spotify I can change tracks with my steering wheel. Module link
