I have 2 LR4. One in South Korea is Diesel 2014 and one in Kenya is Petrol 2012. Recently one in South Korea got water leak on sunroof and when I make a call using bluetooth the other side is hearing Robot voice. Then yesterday one of other LR4 in Kenya seems to be having exactly same issues, Have anyone done replacement of MIC in LR4 by self ?

 

Sorry to digress... But that is quite coincidental.
You're certain it's the mic? The microphone is in the overhead centre console. Just pull hard, and it will pop off. The workshop manual has PAGES of troubleshooting the Audio/bluetooth/telephone system. In my case, a bluetooth module bit the dust.

 

Thank you so much will try tomorrow
