When I turn volume up not getting volume setting display on screen
Also nav stays on Land Rover screen

Has anyone got any info on this problem

Not unknown.

Do a search

I have just checked faults and this was in system

U1A03-62 (6 Vehicle configuration parameter - Algorithm based failure - signal compare failure
Hope this helps if anyone knows the problem
I tried the pushing tuning knob to reset radio but nothing happened
I then tried changing car configuration with iid tool which resets car but still no change

Sounds like you have messed up the ccf if you go into the IDD tool and find the save/restore part and restore the original file that was saved when you first plugged it in it should return the car to its original state or your amp.most circuit may have a fault

The stereo was doing this before I connected the iid tool in but thanks for the suggestion

Sounds like maybe the amp or can you do i hard reset first as it’s simple it is explained in the wiki

Start off by disconnecting the battery for 10s or so. Mine used to do that until I replaced the battery. Sat nav screen would freeze on the LR logo too.

I tried disconnecting the battery but didn’t sort out problem then I disconnected the battery an joined the cables together with jump lead then reconnected live then earth but still the same
Tomorrow I will check the connections into amp
I’ve read some posts listing water ingress causing problems does this happen to the amp

I spoke to a car audio Center today they said could be amp or even Bluetooth module
Not sure if related last week I tried used some cloths I keep in cubby hole where Bluetooth module is and the cloth was quite wet
Do the sports have problems with water getting in around this area and could this be the cause of my problem ie water has got into Bluetooth module

I guess their concern is that the optical network is broken, so the sound doesn't get to the amp.
They have a good point.

Is the bluetooth talking to the headunit ok ?

I’ve tried 2 different phones that are paired with the module but neither will connect with it

You can get an optical loop off for a couple of quid to disconnect the Bluetooth And see if sound is restored

Thanks for reply 👍

this is for the L322 but the same applys to yours,
