2004 Bora audio setup help

[MCiN7]

I can recall my old sony head unit had one of these fitted:

On removal the signal dropped a fair bit.

I used to run a couple of Strathfield Car Radios workshops for about 4 years back in the day and am happy to help out. To give the best advice, it's best if I see photos of exactly each issue..

Wiring harness: Aerpro are the main company in Australia that makes & sells stereo head unit wiring harnesses, see if they have what you want, they are sold in many outlets like SCR, Auto barn, Supercheap Autos, etc, and could order it in for you:
Harnesses - Car Audio Accessories AERPRO

Blue wires: There are usually 1 or 2 BLUE wires coming out of a NEW stereo wiring harness, which are for a) signalling an amplifier to switch on (the whole time the stereo is on), and b)switching on a small antenna signal amplifier (which only gives out a positive signal while the radio is on).

The only problems I've seen with using a wiring harness are usually just the two positives needing to be switched around sometimes. So the Yellow and Red wires, which are Constant Positive, and Accessories/Ignition Positive respectively. If your radio won't save radio stations or any other settings, these two wires need to be swapped. You can just pop the pins out, swap them over & pop them back in.

Also, the best method for keeping the wiring in place to put the original head unit back in is to just 'tap in' to the original wiring harness, don't cut it off. Then, when it's time to re-install the original Head unit, just cut off the 'new stereo' wiring from where it was attached to the original car wiring loom, and tape up neatly the stub of solder left behind..

please don't use ****ty 'clips' like this... they will cause problems..

Bad tapping in, use solder & tape instead!:



You can use 'plugs' and if done correctly, are perfectly fine instead of soldering..

another method: you can always cut and solder the new stereo in, and then when it's time to re-install the original, cut and solder the original plug back on.. there's no shame in it.. it's hidden! But you will want to cut off the original plug so it has more wiring to play with when you have to re-connect it.. a bit more than this picture is desirable, maybe at least double that length..

Ok. It is my intention to fit a rear view camera with my new double din jvc.
This is the problem....
I was wanting to use the iPhone link option ( a cable that consists of a USB,and red white yellow av connectors ( all of which have to be connected at rear of unit. )) as the unit only has one set of av in, can I achieve both the camera and iPhone ?

Hey guys,

Try going into an Autobarn close to you and ask them for some aerpro wiring harnesses. They use the factory wiring and plug n play to what every unit you need. Ie pioneer clarion or jvc. I'll look up the bora today at work as im just about to start.

It saves cutting and joing!

Sometimes you just gotta connect the wires. I changed one pioneer unit for another pioneer and they had different plugs going into the unit. They probably were more than five years different (just a guess looking at the difference in feature).

The wiring is alot easier if you have the manual with it. the only wire i couldn't attach was the dimming function cause the head unit couldn't do it aeropro is good

This explains most of the common colours

in terms of connecting the iphone and rear view camera you might be able to get a double adaptor from jaycar or somewhere but its probably more of a software issue whether the head unit can do it. Just use blue tooth to connect the phone?

Any ideas how many m of 0guage I should buy was thinking 5-6?

RE: rear view camera & iPhone:
The connectors are called 'RCA' connectors, and by the sounds of it, you MIGHT be ok...

Option 1: I'm assuming that the USB can deal with the iPhone.. and the camera only needs the YELLOW RCA which is video input..

Option 2: If the iPhone doesn't work from the USB (though it should), then it can just input Audio (no controlling it) through the 2 Audio RCAs, RED and WHITE.. the RED one is for RIGHT channel Audio, the White one is LEFT channel Audio, and the YELLOW is VIDEO.. so technically, you SHOULD be able to connect them all at once.. If the Head Unit has issues (it shouldn't, they should be separate sources in the controls) you will need to find some kind of RCA switching device..

RE: 0guage: it's pretty expensive to waste, maybe measure it out with some string.. like the 'actual' route, and then add a bit..

Thanx for that. I'm surprised about the iPhone connectivity in the unit; it will work iPhone audio ( 2 way) but the website says that in order for video to work it requires this special jvc cable ( the dual USB RCA one. Tbh I can't quite understand how this couldn't be done through USB. Ill measure out the zero gauge as you suggested
