This is one amazing stereo. For starters, the audio quality of the unit is great. It has a very nice "listening position" feature that allows you to select where you sit in the vehicle for optimum sound, and I found it to be quite effective.

The Navigation is excellent, but during the process of updating the module on my Laptop the unit locked and there is no way for Sony or TomTom to unlock or reload the module there should be better mangement software for the module other than waiiting...
