Hello all
I have got a question about upgrading the audio in my 2002 Omega (Opel variant)
Currently I have the NCDC 2015 radio with CID and buttons on the steering wheel (non-bose).
Question is - if I were to upgrade the radio to an aftermarket option, do I need a canbus decoder like connects2 or can I just use an ISO adapter and give up steering wheel controls? I just wish that the trip computer data could still be displayed.

Cheers for any information!

The easiest way to do this is to use an adapter to retain steering wheel controls, and to swap the CID for a MID.  You will also need a new wiper stalk* with the MID control buttons on, and the MID needs to be programmed to match your car specs.

Without the NCDC, you cannot control the CID at all, and you will get a security message pop up every few seconds in most circumstances.


*Some cars seem to need the wiring run from said stalk to MID, generally much later higher spec cars, but it does vary.

Thank You for the reply!
Sounds like a sad situation since parts in my area are sparse and access to tech2 is quite difficult to achieve.
I might look into taking up a project of using an arduino to manipulate the CAN-low and CAN-high signals to control the CID but until then I am going without trip computer data.

A proven alternative is to hard wire an aux input into the CDC unit.

You can then either use a 3.5mm phono jack to run audio from your phone, or alternatively a pair of RCA jacks fed from a modern single din Bluetooth head unit mounted in the glove box.

You'd probably need to understand how the security pairing works between the screen and the other components in the security loop (Radio/Nav unit, Cd Changer and Telematics unit)

Not to mention Bose if fitted.

I mean, what are the odds

Steve, I can read, but thank you for taking the time to clarify. I hope it didn't take up too much of your evening.

I also have some questions to post on the NCDC theme soon, but will let this one run for a while so save any confusion. 

Looks like theres been enough already.

I think my problem is I shouldn't have tried to fit it to an astra in the first place. We live and learn 
Right, I'm just off to fit the AR25 someone told me should be a straight swap

It's in foreign, think the original was Russian but also seen it in Czech and Polish over the years.

This guide is arguably more useful than the YouTube video that simply flashes through the pictures.

Can personally state that it works as advertised having done it to both Bose and non Bose units.

Unfortunately adding an aux won't suffice for me since I have an android head unit laying around and I wish to utilize it.
However I have found a pretty comprehensive tutorial on youtube about tapping into the CAN-bus via the OBD port with some python code and detecting packets for certain functions in the car. And the example is done on an Opel 
I can share the link if anyone else is interested.

That certainly sounds like a project
