This stereo is awesome and worth the money. The Bluetooth is great around town, but is basically useless on the highway due to the background noise. The only other grimp i have, is that you cant name the radio presets like on older Xplod models. I have this stereo hooked up directly to 4, 3way pioneer 6x8's, and a 350 watt kenwood amp with a 12 inch planet audio sub, and the sound quality is far superior to my old Xplod stereo. I have the XA-110ip ipod controller hooked up it, it and the navigation is okay, the sound quality is perfect.
