My nav screen/audio control unit has gone wacky. It will work very occasionally but mainly the screen shows the Range Rover logo for a few seconds and then shuts off for 60 seconds and then repeats the cycle.

I bought a new nav screen and audio control unit. There is a blue headed coaxial line going into the nav screen and a black headed coaxial line that plugs into the audio control unit.

I removed the old nav screen and audio control unit. When installing the new components I can’t find the black headed coaxial line for the audio control unit. (There is a bundle of lines that includes the blue headed coaxial line for the nav unit. It has the blue fiber double plugs with orange insulation and one line with a grey square plug with a small red wire attached but the black headed coaxial line is nowhere). It has disappeared. It is lost. I spent two hours trying to locate it. It must have dropped somewhere. No luck. Does anyone having a routing diagram or photo or instruction on where it routs.

I am stuck. Phil in La Jolla, California.

2010 Range Rover sport hse 5.0.
