Had a JVC unit in my dash, but wanted built-in nav fratures at a good price. This unit is superb, sounds even better than the JVC Bongiovi unit, and way better than the factory stereo. Unit is easy to hook up, only extra I installed was the antenna for the nav, does not seem to need any other sensor wires for accurate location.

As for the sound, I am hearing details I have never heard before on my MP3s. The voice feature on the nav is handy, as is the ability to use the nav away from the car. Add built-in Bluetooth, and you cannot go wrong with this unit. A great chance to own a unique car stereo.

I replaced my existing 7-inch multimedia head unit without a nav which I found somewhat useless when you need to go to a place not familiar with.
Well, thanks Sonic for selling this at this price.
For me this unit is pretty and and really go well with my Honda Pilot.
The screen is removable and can be used by itself. The nav is very accurate and can be updated easily. Except for a lane guidance (which the unit doesn't have) I think it has everything that most expensive ones have.
Although its screen is only 4.3", I did not miss the 7" screen of the previous unit.
The ipod/iphone interface have some inconveniences but does not bother me at all. Like your settings will not be remembered once you remove your key from the car. And, something like it limits your ability to look for your music files beyond a set amount while the parking brake is not engage as what other owners have noted. However, you can still select the playlist and the shuffle mode.
For the video, if you have an overhead video screen you can connect this unit to it and even though the screen is blank when the car is moving, the passenger on the back can still watch the movie.
When your in the radio or Ipod mode the screen is simple white with just the info of what is playing. The time is in small characters at the upper right corner.
I tested the bluetooth connected to my blackberry and its very clear on both ends.
So far, I did not regret buying this head unit. And it does worked for me.
I hope this review like what others did, can help anyone to decide if this unit is for you or not.
