Range Rover Sport L494 Audio/Nav Problem
Problem:
Range Rover Sport Audio System not working / options are greyed out. Navigation doesn’t load and is stuck on initializing.
Fix:
In order to conduct a fault finding you will need some Fiber Optic loops. Once you have the loops, you will then need to bypass each module along the fiber optic line.
Fiber Optic Loop Design”Remember! If one module is faulty or has no power, there will be no light outputted to the next module. AREA OF INTEREST”.
TS (Touch Screen) -> Audio Control Unit (CD Player) -> Amplifier -> “Navigation Module; Japan ONLY” -> DAB or SIRIUS Module “US ONLY” -> “Optional Equipment; Rear Entertainment system -> Instrument Cluster -> Fiber Optic Diagnostic Port -> Back to start (TS).
Light must transmit from the TS Module through the fiber optic and back. I.e if no light is detected at the cluster then one module is faulty alone the loop.
Once the Faulty module is identified double check the power to the module. if there is good power and ground then module must have internal fault and must be replaced.
Remarks:
Replace module OR wires based on findings.
Module Locations:
TS: Main Touch Screen assembly. Dashboard.
ACM (Audio Control Module: CD Player Unit Dashboard.
Amplifier: Under the carpet – Left hand Seat.
Navigation Module JAPAN: Under the boot carpet.
DAB or SIRIUS: Under the carpet in Boot – Left hand Side.
Rear Entertainment System: Under the Carpet – Boot.
Instrument Cluster: Above the steering wheel.

BMW E9X Electrical Power Loss
Problem:
Car randomly losses electrical power and turns off or while it’s parked. No light, no nothing. Battery is perfect (load tested). There is power at the jump start connectors.
Fix:
There is a design flaw in the fuse-box located in the glove-box. Essentially what BMW did is make the fuse-box connection to the battery cable a simple plastic clip, instead of a bolted down connection. When the car is driven, the battery cable gets jostled and electricity arcs between the connection, and does one of two things: fries the connection, or disconnects from the box. This can be temporarily fixed by opening the glove box, removing the fuse box cover, reaching around the back of the fuse-box on the right hand side and jostling the cable until it regains the connection. This will at least make the car temporarily drive able, but it may lose its connection again.
Remarks:
Replace Fuse-box.
