Thanks for the reply, which is weird is that the audio, radio, screen is working, the only big issue is that the radio, audio, and Bluetooth re-starts every 10 seconds or so.

George,

Is the screen rebooting? Aka, does the logo reappear? Or is it freezing and resetting in the touchscreen display?

Also, what year is your LR4? Cause there’s a BIG difference in what modules are where between 2010/11 and 2012+ LR4s. (It’ll help to narrow the problem down.

Yes, it is the screen rebooting every 10 seconds, the Landrover logo doesn’t reappear and it is like resetting the screen because when in reverse even the camera goes on and off in seconds, radio when rebooting goes to 87.5 and the in a second goes back to the radio station I put it. When radio is off you can hear the noise that the screen is rebooting.
If I try to start the navigation it doesn’t go to navigation because the screen goes back to home. If I try to go to any other setting screen it goes back to home. If I try to pair a phone it goes back to home when rebooting.
My Landrover is 2012 LR4 HSE Lux.
I found in other Range Rover forum that other cars had the similar problem and about 5 people claim that the issue was resolved when the when to the Dealer and got a new Key Fob.
I’m trying this next, I bought the Gap tool G3 and I have another OEM key fob that was from a previous LR4, I’m going to program it and see what is going to happen.



Thanks,


George,

From what you’re describing, it sounds like it’s the touchscreen display that has gone bad. If it were the audio unit, I don’t believe it would be rebooting. You can try the key first, but a used touchscreen is only $100 or so from eBay, so thankfully, not crazy expensive. The good news is that they’re plug and play, so find a decent one and try that. FYI, and screen, 2012-2016 will work. It doesn’t have to be specific to a 2012. The only other possibility I can think of is the Instrument cluster. The CANBUS runs from the IPC to the touchscreen…if you’ve developed some sort of issue there, then perhaps it’s causing the system to reset. That said, I haven’t really seen that before and I’ve seen plenty of failed touchscreens.

Just so you know, in the 2010/11 LR4’s, the audio unit controlled everything, in 2012+ models, it’s the touchscreen that controls all the other modules. That’s why I needed to know year model.

I’m not sure but I don’t think is the screen because I did remove the fuse for the radio, phone, audio, Bluetooth and after I removed it the screen doesn’t reboot, I can surf the other windows but I can not set up anything because the radio, navigation, Bluetooth are off.
I will try something else after I do program the key fob first.
Thanks for the help and replying my posts.



George,

Sounds reasonable enough, probably about time to grab a used audio unit from eBay and swap it out.

Although, if you haven’t pulled the units out to check and see if there’s some obvious signs of damage or corrosion, I’d do that first. It might not yield any results, or it may point you to the exact problem. Either way, it’s a free first step that doesn’t take but a few minutes to do.

Could it be in Valet mode and therefore reduced functionality? Skip that - I see it's always there :-(.

I agree with Tapps33 - it's time to pull it apart and start replacing parts, I'm not sure why you've not gotten in there already but per my previous post there are videos that can help and in Tapps33 you have the guy who knows a lot about this topic. Let us know if you need help wrenching?

I did try the Gap iidtool G3 thing today and unfortunately the tool doesn’t let add a New Keyfob it says that the option maybe locked and o need to contact GAP about it.

Yeah, happened to me. Contact GAP and they send you a flash and then it’ll run a different key fob routine.

Go ahead and read your ECU info so you can send it to them, that way they know exactly what they’re getting into. I just usually email it to myself via the app, then send it attached to my fast last request.
