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.
