This unit performs well all of the features in the description, and the sound quality is good. Navigation around the different modes is not always intuitive, but with a little practice you can get to where you want. There are some features that can only be accessed by using the remote (fast forward/reverse the cd, tilt the screen, etc.) which is a little inconvenient when driving. The GPS works well but no manual was included - hopefully I can download it somewhere. I was suprised there was no jack for an iPod or MP3 player - it was not on the feather list but they are found on almost all steros these days.
I ordered all the recommended installation accessories and received the wrong wiring adapter, so double check to make sure that you are ordering the right one. Once I had the correct wiring adapter I was able to install it myself with not to much difficulty - the wiring was rather complex but I followed the directions and it worked fine. Overall this unit is very good value for the price - a unit with similar features costs $800+ at retail stores.
