I have just purchased a new Sat Nav Unit and would like to connect my original Radio Antenna to the Sat Nav Unit, so that I am able to pick up Radio Stations and control their output via the Sat Nav Unit.
Radio Antenna Cabling
This is how the Radio Cabling currently looks:
As per the image, we can see there is a Black Wire that is then connected to a Blue Wire and then there is a Red Wire that is connected to another Red Wire with a Fuse inbetween.
How do I then connect the above Wires to the below Power Cable that came with the Sat Nav Unit?
I assume I would need to use some kind of Splicer to 'tap in' the Radio Antenna wires into the Power Cable wires?
With this in mind, could someone advise on which colour I would need to 'tap' the Red Wire into and which colour the Black/Blue Wire would need to be 'tapped' into.
Power Cable Colours ...
- Black and White;
- Dark Grey;
- Dark Purple;
- 2 x Orange;
- Blue & White;
- 2 x Green;
- Pink & Black (With a 'Key 2' Label attached).
Previous Power Cable
I can see that the previous Sat Nav Unit's Power Cable has indentations, from the Splicer, on the Blue and Black Wires. As such, would it be fair to assume that it is the Red and Black Wires that need to be connected to the Radio Antenna Wires or should I ignore the original setup?
Do I need to concern myself with grounding any of the Wires? When I took out the original Sat Nav, I could see that a Power Cable's Pink Wire had been cut and stripped and then wrapped around a Screw on the rear of the Sat Nav Unit. Is this Earthing or something else that I need to be aware of? Any guidance would also be appreciated on this matter too.
I have contacted the Suppliers who have stated that they are unsure and are not able to provide any guidance on wiring. Furthermore, the Manual does not give any details on wiring configurations; hence trying to figure this out for myself.
Any assistance, would be greatly appreciated.
