Yes, that kit is all I had to use for mounting the unit. You can actually take your factory radio out, trim the plastic inside the dash I spoke of earlier, and install the Z1 w/kit without taking off the bezel (the silver piece that holds the vents and switches and knobs. But, if you want to take the radio back out you have to take the bezel off.
I clipped the microphone to the edge of the headliner right beside the little overhead console that has the two lights, the little compartment for the garage door opener and the moonroof switch. I just tucked the wire inside the headliner and over to the passenger side and came down the pillar behind all the trim. You can get it through to the area behind the glovebox after you pull down the rubber door moulding. I put the GPS antenna at the rear of the roof and ran the cable around and into the moulding at the side of the rear hatch opening. I then ran it along inside the headliner trim to the front and met up with the microphone cable.
if you are having someone else install it, make sure he solders and heat shrinks all the wires from the h/u to the harness, don't accept butt connectors. The wiring is very straightforward, so he shouldn't have to be making any changes to his wiring.
One word of advice on the dash kit. If you use the rounded head screws, the radio will not slide into the dash (wanna guess how I know that? LOL), but the flat beveled screws are barely to short. I had to use the rounded screws to make indentions in the plastic of the kit and then use the other screws. I guess you could go to the store and find some screws with the same head, just longer. It was too late when I was doing mine, so I improvised. I used 4 screws in each side of the radio/dash kit. Some might say it's overkill, but I didn't want that much $$$$ banging around in the dash ;)
