just making sure before I go through with all these purchases that this navi system will not give me problems. I am planning on overhauling the whole system, just wondering if anyone has experience with these cars. kind of hard to find info on hu's that fit, just want to make sure everything is right. pioneer premier hu, and 6.5 components. crutchfield and best buy say the components fit for sure, but i am having trouble sizing up the hu. also if I have overlooked anything someone plese let me know. thanks
