installation of double din headunit into VY. Advice??

[mamejay]

Hi Everyone,
Long time reader of the forums.
I have just upgraded my VS to a VY Acclaim.
I have just purchased an all in one double din headunit with DVD, Digital TV GPS etc.
I have purchased a fascia to fit my commodore.
The new head unit uses a standard ISO connector.
The new unit has steering wheel controls option VIA 2 wires.
From what i can find on the net the original head unit has a standard ISO connector also but there is another connector above that. See the picture attached.

Does anyone have the actual pinouts of all the connectors in the ISO and the additional connector?
Also where have some of you mounted your GPS and TV receivers and what do you find is the best path to trace the receiver wires back to the head unit?
Last thing for the steering wheel controls. Which pins are related to that in the connectors?
Any advice or a link to some good guide would be awesome.
Thanks everyone!

Thanks to all of you for your comments!! The unit already came with a ISO connector so it basically just worked. Just needed to attach the illumination wire to the head unit ISO connector and I was all set. Got it all working perfectly except for the steering wheel controls.
On the new head unit it has two wires coming out the back of it labeled steering1 and steering2.
In the setup of the head unit you can hold a steering wheel control button then set the corresponding button on the head unit.
I cannot get it to register any button presses. I tried connecting each on to Steering REM and REM GND connectors but did not get anything. This is a standard Chinese head unit that you can get from eBay nowadays.
Has anyone had any luck with a head unit like this before and the steering wheel controls?

[Nic92]

yeah, it didnt work for me either with the steering wheel controls

[mamejay]

Would I need to just connect ground to REM GROUND and only connect one of the steering wheel cables from the HU to the STEERING REM?
I have seen others who have gotten this to work but they have not elaborated on what they did.

[Nic92]

umm, i dont no. didnt work for me, so i just left it

[heyitsEnricoPallazzo]

It is probably canbus.

[mamejay]

Ok. I have done more testing and got it working perfectly.

On my head unit I just needed to attach one cable from the head unit to Steering REM and ground the Steering GND.
Once this was done the headunit could be programed with the steering wheel controls.
The unit it now all installed and working perfectly.
If anyone needs a hand with there's just let me know.

Did you have any luck with the steering wheel controls ?

Sounds like the interface on the HU side might be the 3-wire CAN-bus based ones, i.e. ground, control1 and control2.

I'm currently looking at one that has that type of interface and looking around to see how it might be integrated into the VY steering wheel controls.

Any advice would be appreciated.

Thanks,

Jim.....
