Hi all:
I've spent countless hours troubleshooting this issue and scouring the web and nothing seems to work. I'm hoping for some feedback here.
A few weeks ago the radio quit working in my LR3. There was no sound for a number of days. After about a week the sound came back on and worked for about 3 days. The radio head unit and nav work fine. I can change the channels and input, however there is no sound. No volume icon displays when I attempt to change the volume. Same thing with the NAV. I can input destinations and it will map to them, just no sound. Same thing with bluetooth. It will connect and receive calls, just no sound.
Here's what I've done to this point:
2006 LR3 Sport
Pulled and checked the following fuses both visually and with a fuse checker. All the fuses were fine and in good working order:
Fuse 42: Audio Amplifier
Fuse 43: Radio Frequency Receiver
Fuse 53: Multi-media module, audio unit, DVD player, Video Display
Fuse 58: Telephone, touch screen display, multimedia module
Did a soft system reset by disconnecting the negative battery terminal for 30 minutes. I did this twice - no change in problem.
Did a hard system reset by disconnecting the negative battery terminal, then positive terminal, and connecting the two together for 5 minutes - no change in problem.
Took out the head unit and nav unit to check for loose connections. Disconnected all the wiring and reconnected - no change. There is only one light coming from the back of the fiber optics on the head unit. I've attached a pic, I'm not sure if both are supposed to be lit up or not?
Inspected the amp under the passenger seat. No loose connections. Disconnected the wiring and reconnected- no change. There is only one light coming from the amp wiring. Again, not sure if both are supposed to be lit or not?
Any suggestions? Are there any fuses I've missed? I know on some searches I've done apparently RR have an amp fuse? but I didn't see any other fuses behind the radio head unit, nav unit, or the amp.
I don't know what else to do. Pics are attached of the fiber optics lights. The head unit pic is upside down, so the side that lit up is the passenger side.
