Hush

OK sorry I mistook the grey block connector, the one in photo must be the old backing camera plug, it gives 6v only when car in reverse and has no where to plug in on new stereo, looks very similar to the rear curtain one and the aircon control plug but def not for them. Ureka I think I am onto something.

Well the reverse camera bogie still lives.

So I have read so many pages from different sites looking for the answer to a much asked question.....where is the backing light (reverse) wire in the dash? Strangely enough on my 2007 Aurion Grande it is the red wire that powers the rear window curtain! Not sure why I would need to have that powered when reversing but I tested it a heap of times and every time I put the car into reverse I got my test light to come on. It still hasn't cured my reversing camera issue but at least I know it now has power.

So having read a lot about this issue of having no backing camera and having the same issue on my new stereo, it seems the camera is 6v and the car is 12v and some clever person has designed a plug and play connector which switches the voltage. It costs $14 NZ including shipping so I hope it works when it arrives. I also hope it has a positive effect on my non working GPS unit.

OK I think I have found the issue, the original backing camera is 6v whereas the rest of the car is 12v, the new stereo unit will be 12v and has no ability to drop the volts to 6volt. I found this little gem which may allow me to have the backing camera and the navigation working. It connects directly to the #24, 23, 22 pins from the original Toyota plug which is the wires for the backing camera. For $14 NZ delivered if it doesn't work I won't be too out of pocket lol.

Hey Tony, finally got that downloaded on my partner's PC but it was just a list of numbers? Cheers anyway mate.

Can you dial them up manually then hold your finger on it until it becomes set?

So radio in and happy with the look but still no backing camera and I know it works cos it did on the old stereo, I am having issues finding the correct wire to hook it up. GPS/Navigation is still not a go, I will need to sort that.

I think it looks OK for a cheap stereo.

Still trying to figure out the backing camera wire colour and getting Navigation working but stereo is ok.

Well I took my original stereo out and fitted the new stereo since the stereo shop had a 2 month wait to fit it. The new stereo went in easily, radio works great, steering wheel controls work, still figuring out the GPS but I am told if I hook my cellphone up to one of the USB cables that came with the stereo I can get Google maps to work? For a cheap stereo $174 Kiwi (about $120 US) it performs very well. Still haven't figured out the backing camera, the old stereo had one and this new one is able to activate it too once i figure it out.

OK most of it was user error, i had it all hooked up OK but didn't realise I had to swipe the screen lol, I was viewing a Utube video and I noticed the guy swipe the screen, and I'm going "what did he just do"? Anyhow back to the car and found mine worked the same, radio works, GPS may need to upload, backing camera which I have never used anyway fails to work as did the steering wheel controls but some of that could be settings I haven't got to yet. Cheers for your help.

OK so I think I have most things hooked up correctly, I had to bodge the aerial connection as the new unit had a longer each and I couldn't get a decent earth (which I thought was the reason i couldn't get any radio) and now I have GPS which can't find anything but seems to think it is in Israel, I think this may be because I am in my own back yard and not on a road it recognises. I can't get any radio reception at all, in fact I can't find where to look for any radio stations? All I have is the 4 preloaded tracks which work and prove the speakers are hooked up anyway. I wasn't sure what to do with the USB input wires so I connected them to the unit and ran them down the passenger side just in case I have to connect to them later.

I am used to working on motorbikes and usually can find a wiring diagram for them to follow but all the ones available on Google have bugs and viruses. Does anyone have one I can download or copy for the earlier Aurions, mine is a 2007.

Oh yeah I just plugged the car radio aerial in to see where it went. Not sure about this little blue bulb thing, it looks like a bulb?
