Just have a quick question. I am going to install a Kenwood DNN-992 in my 2006. Is it worth it to use the iDatalink Maestro? The factory head unit is not really integrated in the first place like the newer cars are these days. But by adding the iDatalink Module , will that give me extra features (climate control settings, diagnostics, etc.) when those features were never there in the first place ? Any body have experience with the iDatalink ?
