yes, that's all you need.. you don't need to route anything to your trunk, usually places like bestbuy say you need to do that.. you will still get audible alerts when things happen.. like if you turn off the autoheadlights, you will still hear the beep beep beep, but.. sometimes you hear an audible alert and you don't know what happened, that's why i bought the kit with the DIC.. it's ugly, but whatever, if you honestly don't care a bit about the DIC, you should get a 2din screen, will look much nicer.. just my opinion though.. goodluck with the install!
