well i went through a ball ache of trying random peoples "d.i.y" guides on the fitting new stereo to 350z with bose, which all faied. so i went to caraudiosecurity and got them to show me what to do, thus helping others. what a thoughtful guy
A few things to note before you read any more.
1- JVC models 6-8 dont allow the use of steeribg wheel controls.
2- the earthing wire for the 350z is the antenna cable. so dont do what i tried and spend 2hours grounding nothing.
what you need:
-jvc avx640 (hopefully)
-double din fascia (note: pre06 models have different fascia, you need to cut a piece out .. images.esellerpro.com/2517/I/223/7/medscaleshop_large_connects2_b_con-ct24ns04.jpg )
- the iso harness cable... images.esellerpro.com/2517/I/910/medscaleshop_large_celsus_b_cel-ais2260.jpg
- some wire thinners/cutters
-electrical tape
-and the tools req to take front stereo dash apart.
Unfortunately no photos, but ill describe in detail what to do..
step one: the earthing wire (handbrake wire as its labelled), thin the wire to remove about 2cm of the plastic coating. the screw on the back of the jvc stereo wil act as a grounding point, unscrew the screw, wrap the handbrake wire round and tighten the screw into place. covering with electrical tape.
step two: use electrical tape and cover the bue and yellow wire marked "steering wheel interface". this is void and wil confuse you with next step. also tape the black earth cable on the harness as you will not need to earth this.
step three: plug the iso harness into the jvc model harness, then plug that harness into the back of the jvc. (do not plug iso into the car adapters yet). there are multiple wires hanging off both the iso and jvc model. on the iso adapter, there is a blue wire (amplifier bypass), the connecting wire is the identicle blue wire on the jvc iso wire. this wire is plugged into the adapter, remove it by cutting the wire close to the harness allowing a longer reach. (if you dont fully understand read more basic instruction below)
[you have two iso harnesses. one that plugs into jvc model. and one that connects the jvc iso to the car plugs. the jvc iso has a blue wire (amplifier) plugged into the harness. where as the iso adapter has a blue wire not plugged into anything (amplifier) these must be connected to bypass amp. cut the blue wire away from the iso harness so that the amplifier wire would be connected from jvc model, to iso harness, which in turn would connect to car plugs.
step 4: there are four speaker input wires. Red/White/black/yellow. the black wire acts as a red wire, and the yellow wire acts as a white. as you look at the back of the stereo there are 3 red slots and 3 white slots, the black and yellow go furthest to the left slots, nd the red and white slot in the middle slots. these indicate the right/left speakers and the front/rear speakers.
step five: plug the iso harness into the car plugs, and fit the antenna to the stereo and turn on.
to check its all fitted correctly, put a dvd into the stereo. this checks video and sound. go to settings and set the sound to go all the way to the rear, then front, left, then right. now your stereos working all you have to do is fit the double din fascia.
