Hi,
Do you mean the canbus of the unit RQ0422 can suit for your old stereo?
Next,you can use a wire to short the yellow wire and the red wire to find whether the unit RQ0244 start up or not.
Here is a picture you can refer.

Hi,
Did you try to connect the red wire and yellow wire together?
If this does not help,you can try to click settings---about machine---system update one by one.
You can refer follow picture.

I have managed to sort the issue out now thanks, have one more though, my brother in law who brought and fit the radio, but cut a couple of audio out cables so how can I get a replacement audio out leads to clip into the stereo?
