i upgraded from the eclipse 726e. my opionion, if you like it simple with no customizing options and a so-so nav and very little tuning (bass, tremble,mid) then the eclipse is a decent unit.. now for me i need the customizable stuff the big eq, easy upgrade of software sms texting and it is a little hard to get use to but the dnx 9140 is wayyyyy better then any deck out right now.. i dont like pioneer not an option for me.. and the eclipse 5v pre out is like 2v.... for real. big diffrence from older eclipse and kenwwod, they lied on that 1.. lol
