I got this for my birthday along with a Sony rearview camera. The radio was an upgrade from the factory unit in my 05 Frontier.
Like; Screen size, picture quality, USB on front, Aux on front
Dislike: slow processing between functions, on screen file access and navigation, slow to change to the rearview camera.

After about a month of use the unit began to flicker everytime I hit the break. I had the installers triple check each connection and contated Sonic. But still had issues figure out what was causing the surge.

I sent it back and was notified that the unit was discontinued. Decided to try the BOSS BV9999BI. Very similar functions except the Boss has a mini usb port, no expansion for Navigation and has an increase in in power.

I got this unit for Christmas and I install it to weeks latter only to find out that it came defective, I have a problem with the screen going out and in also flipping out or in, got to send it back, also it takes a while to load usb and dvd, no last memory... Bluetooth work OK but the Mic sound terrible you can hire ok but they can't....remote control it's terrible you got to press so hard and be almost in front of the unit......no dual zone control..and really cheap interface on the screen... overall onces you got it going on were ever you want to do its ok....if you are on a budget and don't got any other choice get it ....I got me a pioneer and the difference it's like day and night....

You cant do change the song or chapter without opening the screen...
The operating system is poor!!!!
The images on the background are really poor quality...
Power Acoustik PTID-8970NRB is a better option in my opinion
