Every company salesperson i talked to said i need expensive harness too. That stereo is a step above mine but i cant see why the cheap basic harness wouldnt work.
The only difference between mine and yours is the 6 disc and outputs for dvd.
They said even for the lower end factory stereos it pac module was needed because of the canbus computer system. BS. Everything works the same on mine, even the radio staying powered until the doors open.
If you have steering wheel controls though, you will need the steering wheel interface for that.
