Installation was reasonable. Unit comes with an external microphone and has good sound quality. I just did a software update from 1.5 to 1.7. I have both USB and microSD memory chips with my music on them, navigating them with the touch screen is great. HD Radio is very nice with 15 presets. Pandora and streaming bluetooth work great. I even put in the ipod cable for the wife. I was able to watch Tommy Boy while waiting on the wife to return something at Macy's. I'd recommend this unit because it is very powerful but very easy to use. It does what it says it does and it accommodates many different installations. It is very fast, for example I was able to drop in a GPS destination while at a red light in about 6-10 seconds. Very cool.

i really love this system. it does everything i want it to do and more. just the only slight problem with this system is the bluetooth sometimes searchers for my phone but its really not about at all. i would recommend buying this Kenwood.
