Hello all, looking for some advice help.. 2013 lr4 hse lux with rear monitors. I am having trouble connecting Bluetooth. Since I have owned it I have not been able to connect. I see discoverable at times. I try over and over to connect with no avail. I also hear popping in the speakers. My rear monitors dont come on. I have tried swapping the front screen- that resulted in nothing. I changed out the receiver- that did nothing. I can see the red beam in the front display, receiver, amp in the rear passenger side and the rear entertainment module all have working MOST signal. Also my touch screen times out quickly and reverts back to the home
screen sometimes not even giving me a chance to manage the buttons. My signal for the radio is chopping and it comes and goes. When I pull the power to the amp the infotainment front screen does not time out and acts normal with the exception of no signal. Plug it back in and it all acts funny. Where do I go from here. Just want the radio to play so I can hear all these speakers acting as they should. Thanks

 

The MOST network is about sharing data… it seems your central system is having the issue.
Do you have any diagnostic tools?

Also, a common issue is water damage if the sunroof ever leaked… or water on the floor…

 

Central system meaning receiver? I changed it out with a different one. What are the chances the exact same problem followed with a different receiver that looked practically new. Aside from being an over a decade old I did not find any traces or water egress or anything to lead me to believe it would not work. Same with the factory unit.

 

Also what type of diagnostic tool would I need for figuring this out. I have meters and lights and all sorts of stuff basic car related

 

LR diagnostic codes from ODBII.

 

This should get you started. Also look at the Workshop Manual, section 415.
