Extremely useful option. GPS nav without interruption of music. Superb display!

I got this for a ddx516 and it does exactly what i intended. This is the second time i have ordered from Sonic Electronix and I will definitely continue business with them.

The system needs to be udated atleast every two years, but it works great! had about a year now and have not had any problems. installed it myself took about 3 hours. very easy to navigate threw perfect add on feature

While I have not used any other gps brand and cannot compare it with them, I can say it functions well and looks good. I do not like how the map constantly adjusts the aerial view and the program that keeps up with fuel mileage does not work right. It does have many other features that work good, with thousands of POI available.

Product works so not very fast or accurate with maps.

Was very happy with their nav add on and great price and delivered what I wanted, still working great.

I love having this in my car. My screen makes it so easy to read and use. It was pretty easy to install and no issues while doing it. Has taken me everywhere since. I just wish the kenwood radio that I put it in had already been ready for just a turn on with out having to buy the seperate module. Other than that, it's been great!

I ordered this unit to replace an aging 7100 so the navigaion would be "current". It installed easily with the existing 7100 wiring harness.

Pros:
Controls on faceplate easier to use than 7100.
Rotary vol knob is highly underrated.
Display is crisp.
Cool to be able to change color of hard buttons.
Audio is clean and undistorted.

Cons:
Navigation is slow.
Bluetooth integration is weaker than its predecessor. Newer Blackberry cannot connect.
Bluetooth telephone is horrible. Almost everyone I talk with over the bluetooth hands-free complains about the background noise and lack of clarity of the sound or noise. Incoming audio seems fine.
Touchscreen seems to have a mind of its own. The other day, I could not press a button and had to turn car off and reboot stereo. Very frustrating.

This is my 5th Kenwood in-dash since 2001. Each generation gets more graphics, more features, and yet the quality keeps getting worse. I do not envision another Kenwood in-dash system in the future.

This Kenwood/Garmin navigation system is excellent. The installation was easy and the unit is extremely easy to use and well laid out. I find it far better than my old Garmin portable unit I have. Everything you need is in the package along with good instructions.

I purchased this unit for my Kenwood DDX-616. After a hour installation it was working flawlessy. The best Garmin navigation unit on the market packed with tons of easy to use features. Overall, a Great buy and a priceless addition to my vehicle.
