Really not too difficult for a simple "head-n-4" installation. You will be completely replacing the whole system, so you don't have to worry about using the existing wiring.

Head unit is not hard to install but I didn't have the bose system. Best Buy installs head units for free if you purchase from them, but you have to pay for and additional parts such as a dash kit. Just don't mess up your dash when you pry up your vents on top, I believe there are two screws behind them. Nick
