i have this headunit and love it to death. i could here a difference in sound between my old cheapo jvc. took me a few days to figure the head unit out as there is menus within menus, but once you get a feel it easy. i still am adjusting settings seven months after bying this head unit, that just goes to show how many audio settings there are. some negatives about the unit in my opinion is the flimsy buttons and it gets hot after a while (over 30 min of use), but i have never had any problems related to that. awesome review and for the help a few months ago figuring the unit out OP.
