I have a 2006 range rover sport HSE but no sound coming from my speakers but my radio is working visibly.
****I know this has been asked on here before as I have followed all the advice already given to no success.****

It may be worth noting that unfortunately I don't have Bluetooth so don't appear to be a mute issue. Also the volume control knob worked as in it displayed the numbers the volume would be on, but has now stopped working!! And sat nav stuck on LR screen constantly

I have attempted the following already;
Checked all fuses (fine)
Removed amp and had it checked by a specialist (in working order) also red light shows on fibre optic
Removed radio module from boot all seems fine no water damage or loose connections. Red light on fibre optic
Removed negative battery cable for 30mins no success
Remover both battery cables and done the holding together method. No success

Today I removed the centre console and took the radio out. NO RED LIGHT on fibre optic. I am no sure if this is the problem nor do I know the next steps to resolve this issue. However, would the radio still work if there was no power in this fibre optic? Does anyone know? Or had this issue? Where does the fibre optic come from to the radio?
Are there any fuses in the radio itself?

I attempted to open up the radio to look for any faults but found it difficult to open fully.
I had to drive 10hours without sound :-( and this problem is really buggin me.

As usually dealer has never heard of this before even though it seems very common; and there suggestion was to folk out on a new amp which I have already established is in perfect working order.

Any help would be much appreciated. Thanks

This may be the dreaded MOST "loop" issue that was relatively common on some early MY06 models. It requires reconfiguration of your infotainment system software with patches loaded via approved diagnostics, to fix a loss of communication between modules that basically causes your infotainment system to constantly reboot... Think of it as a computer with corrupted operating system files. Even though the attachment below is a bulletin issued for NAS vehicles and it sounds like you are in the UK, a similar fix may apply in your country.

That would be the best case scenario. Worse case would be a blown audio amplifier.

Yeah, I am thinking that for the screen to get stuck on the LR logo it's more likely to be a software bug. But within the MOST optical ring, it could be any of the connected devices (screen, amp, BT module, etc.) causing the issue. Really hard to troubleshoot without hooking up the car to diagnostics.

Thanks for the responses. Don't know if it makes a difference but sat nav wasn't stuck on the logo screen originally, it became stuck sometime after the no sound issue. It would offer the menu screen 4x4 info/ sat nav etc but when selecting sat nav it said it was no a sat nav disk. It froze after I tried a 2012 disk I borrowed.

I guess it looks like there is no way to sort this myself and I'm going to have to have a very expensive trip to LR.

Thanks all the same.

OOOh, put your old disk back in and see if it works. I think Those Disks are serial number specific to your vehicle's Denso unit.

The nav disks are not serial specific and interchangeable between 06-09 FFRR, 06-09 RRS, and 05-09 LR3. If using a backup copy though, it has to be burned around 2x on a relatively high end blank DVD or the nav system won't read it.

Thanks to all for your replys. I have had brief diagnostics done for free, which cannot read the radio. I assume this is as a result of having no fibre optic (Red light) to the radio. Does anyone know what unit the fibre optic comes from before the radio???

Any help would be much appreciated. Many thanks.

Is this Software update as mentioned in the technical bulletin No: LTB00179 done by the dealer for free or does it cost us for their precious time? I am having the exact issue mentioned above but not sure how folks got it resolved and did it cost an arm or leg. The issue is intermittent and I even tried another key (another post suggested that) but the issue popped up again. Thank you all in advance for any input.

I've had this same exact issue. I was so fed up after a long drive where I had to talk to my GF for over three hours (lover her but, those long drives suck without a radio).... I went to the stealership. I got the gamut of excuses; everything from corroded contacts to software updates needing $400 to install! I was furious because, 1.5 years earlier they replaced the BT Module for the same issues and when I asked them why they didn't do all these software updates then they provided no competent response. I was in uniform at the time and I declined their $400 service but, they tried to charge me for over an hour of diagnostics and the loaner. I leaned in to the service rep and said, "if you want me to raise my voice in front of all lease people to display your ****ty practices towards service members, I have no problem doing that" I walked out paying nothing! I drove down to the local indy shop and got the software updates for $200; radio works fine now. I am considering upgrading to an aftermarket amp and want to know if that's even possible.

A few have, however it's not just upgrading the amp, it's pretty much the entire system that will need to be changed out. This amp and head unit(and bluetooth, sirius, DVD...) all need to talk to each other with the fiber network in the truck.

After all my frozen navigation and no radio issues for the last three years, I finally fixed it. It was the fiber optic connection at the Bluetooth module. It either wasn’t seated correctly or the module went bad. Either way, I plugged in a female loop and took the Bluetooth module out of the equation. I now a have fully functioning radio and navigation....

There’s no need for the module anyway, the factory Bluetooth sucks.

Where is the Bluetooth / Telephone module located? Trying to locate mine without luck (not sure if my vehicle has it either)
