It doesn't sound like the head unit is the problem here. Can you give more details on this issue please. How long has this been happening? What happened when this issue started? What were the conditions (where you driving, just sitting in your truck listening to tunes, trying to update your software yourself, etc..)? Has the NOV/Radio unit ever worked properly since you've owned the vehicle?

 

Hey,

The unit has had a few quirks here and there, but always went away when truck was turned off and restarted. The situation happened out of the blue. My wife and I drove it as normal and the unit was working fine, then we get back in to start up and thats when I got the white screen with bootloader message. No warning of anything. I have not tried to do anything to it (update) or even opening the rear panel prior to this happening. The problem has remained now going into week 2.

Thanks again for your thoughts!

 

Ok cool, that's helpful. When you say it had problems, what kind of other problems did it have? So this last occurrence was all in a day is what you're saying right? Had a few issues, parked the cr for a while, started it up after sitting and whitescreen right?

 

After further thinking on this issue you're having; if you're getting a can bootloader message, this tells us something is going on with your NAV unit in the boot, not your head unit. But I cnt figure out why the radio doesn't work? This is strange. I've been searching VMW forums for models with the MKIII NAV system your truck has and there are a lot more results coming up. If you try to google Range Rover NAV error bootloader, google will probably bring you right bac to this thread since there's not a lot of RR NAV info out there. My advice would be to search BMW MKIII NAV whitescreen errors, etc..

One thing to try; turn your truck off and pop the hood. Close all doors and don't leave your key in the ignition. After your RR has sat fir 15 minutes or more without opening a door ir using the key, open your hood and disconnect your battery. Leave it disconnected for 30+ minutes to make sure the computer fully resets. Reconnect your battery and check your NAV to see if this fixes it. Let me know if that helps!

My independent mechanic apparently has already tried to reboot by disconnection of the battery etc. When I got the truck back from him the clock was off telling me the power was cut for a while. Whats weird about my situation is the the radio plays for 30 sec before it cuts off and the screen goes from white to black. So get in start truck..white screen with bootloader message..radio plays..30 secs all cuts off and goes black. Get in truck with no key..push power button amber light comes on..white screen illuminates with message..radio plays for 30 secs then off again.
This is what I am thinking could be the amp malfunctioning. Not keeping the whole unit powered up. And that is what the dealer is claiming too. He cant update system because unit keeps cutting off. I think the nav unit in the rear is ok. The DVD ejects and no signs of failure there.
I really hate to order a head unit (as the dealer is claiming) and the system keeps shutting off cause of a faulty power source. :think:

Thanks for your continued help!!

 

Hmmm, very strange indeed. Now keep in mind your amp simply takes signal from the head unit, adds power and distributes that power to the speakers. If your head unit stayed on and screen was oj, music played fir 30 seconds then you couldn't hear any audio but everything else stayed on, I would agree with you its the amp. Since your head unit screen is affected and it completely powers off after 30 seconds (this is what I understand the issue to be in addition to the bootloader message) I'm leaning towards the NAV computer software and/or may actually be a fualty head unit. Indy shops are a great resource but at this point I would recommend you take your truck into a car audio shop that has a good reputation in your area and has been around a while. They will be able to trouble shoot this issue further and be able to pin point exactly what the issue is. Sorry I couldn't be of more help, this is definitely not a common issue.

Once they determine exactly what the issue is, please cone back to this thread and update for people in the future with similar issues

 

Can you time it, is it always pretty much 30 seconds on the clock? If so, it sounds as if the infotainment system may have entered "Transit Mode" by itself (because of a software or low power glitch occurred during a system boot or shutdown), which is the way the infotainment is normally shipped from the factory. When in transit mode, IHU turns on but turns off after 30 seconds as security and to avoid depleting the battery while the car travels from UK factory to its final destination. Transit mode is disabled via software as part of pre-delivery prep by a dealer, and usually stays that way for the life of the vehicle, but s**t happens with these cars. If your indy shop has suitable diagnostics, tell them to try turning Transit Mode on and back off via software, and see what happens. ray:

Disclaimer: I have no experience with the infotainment system of your 05, but my 2006 RRS has a virtually identical MOST setup and components, and Transit Mode can be enabled or disabled on my car via diagnostics. Can't imagine your system's software would be that different.

 

Interesting! Now would transit mode only affect the infotainment system? Would trasnit mode affect other areas of the truck as well, such as the suspension?

 

Just the infotainment / navigation system. The suspensions have their own separate "transportation" mode (with the engine off, the airbags fully deflate and the vehicle sits onto the bump stops) so that the car may be safely lashed to a transporter. It can only be enabled or disabled via T4.

 

So I took Danno's advice and took the truck to a well known audio shop that specialize in high end vehices. Ater looking over my system and understanding the issue, they are in aggrement that it is a bad head unit. I mentioned about the transit mode possiblity but the system does not reboot on its own after it powers off so they agreed it was not in transit mode. So I bit the bullet and found a unit on ebay. I have it ordered and should have it by the end of the week. Once installed and a trip back to the stealer I should be back up and running. ray: ray: ray:
I plan on installing the unit myself. I viewed a youtube vid of the procedure and it doesnt look that complicated, just time consumimg. so again.. ray: .
I will let ya'll know how it turns out. Thanks so much for all of ya'lls input and thoughts so far!

Ok. Replaced the nav/radio head unit in the dash. Plugged it in and it fired up with the splash screen,the radio started playing as normal, then in about 30 secs it powered off. ****!!!! My buddy that helped me with the install, who has very extensive knowledge of audio installs, started trouble shooting in the rear boot. He unplugged the nokia phone module that sits on top of the nav unit and the head unit stayed powered up! It stayed powered up with the land rover screen and was inoperable. The amber light just blinks and the unit stays powered up with the phone module unplugged?? So..is the phone module the real culprit here? Once phone module is plugged back in..the radio plays and then powers down after 30 secs. I understand that the whole infotainment system is like a big circuit and with a glitch in one area..nothing works. Obviously since mine won't stayed powered up!!!!
And remember the dealer told me I needed a new head unit too! So would y'all agree the the phone module is the culprit here? If so I'm gonna replace it, get the system to keep power, put the old head unit back in, take to dealer for the boot loader soft wear update, and sale the new head unit I just installed.
Freaking dealer is a joke. Glorified part swappers....

 

I still have no radio! I had an opportunity to borrow another 05 RR Nav/bluetooth module/and amp. Swapped all out of the borrowed 05 and plugged into my 05 and...same ol crap. Unit comes on, plays music for 30 sec then shuts off!!!! Totally frustrated and trying to avoid taking back to dealer. They are as clueless as I am!!! Could it be the unit behind the NAV display in the dash? Is this the readio receiver? Does this unit provide power to the Nav head unit in dash? I am at loss! Any feedback would be greatly appreciated.
Oh btw, had my Indy reset the "transit" mode feature and still no go. :x :x :x :x :x

 

Hello All,
I am a new member but a veteran lurker of the site. I own a 2005 Rover HSE with approx. 84000 miles. I started it up yesterday and experienced basically the same exact issue with the display unit that Brian1999 had. Splash screen cycles, radio turns on, then 30 seconds later the whole display goes dark as well as the amber light. Brian, did you ever find the culprit? It would be great to avoid taking a trip to the dealer (haven't had to yet in 3 plus years thanks to the info on this forum!)...any updates would be greatly appreciated!!!

 

I am also having this same exact issue as "Skitz" and "Brian1999" descibed in this thread. I have replaced the amp and was looking to replace the display but per this thread, that isnt the solution. Can anyone possibly provide any insight?? I understand this thread is super old but I just acquired this vehicle and trouble shooting this radio issue is very challenging. I have reviewed all the other radio issues but none of them are replicate my issue (even the ones on youtube) Can anyone on here help point me in the right direction?

Thanks in advance!

 

Okay, so I went to jump in the car today to test the battery and the battery was dead. Jumped it, took it down to local auto store where they ran the diagnosis, and the came to the conclusion that the battery weaker then it should be but not on it's death bed. Now I am curious if a weak battery was causing my display and audio functions to cut out or if the malfunctioning display is perhaps draining the batter when the car is not in use. Any suggestions?

 

If you wouldn't be opposed to aftermarket solutions, I'll link you to my response in another thread. Not sure if the head units are VIN coded, or if you can do a junkyard or eBay pick. I'm very new to the import world.

Thanks for the info! I am not opposed to an aftermarket unit, I guess I would still like the use the clock and other vehicle terrain info offered by the system (im kinda anal about OEM offerings lol even though its dated). If I can keep both, that would be awesome as my plan was to fix this and install an apple car play interface utilizing phone mirror function. Ive heard great things about the HK 7 system but how will I power it with the aftermarket head unit? Seems I will have to add several x-overs and a few amps. I have also seen some people keep the original radio in the glove box while adding an aftermarket unit.

 

The display unit in the dash that you press buttons and has a touch screen is just that. LR calls is a Touchscreen Display TSD, it has no real smarts other than selecting the various info screens and inputs from the Radio, TV (in Europe) and the Nav system. The smarts of the the system is the Integrated Head unit (IHU) located behind the touch screen on the 05 and 06's, and under the fuse panel on the 07s and up. This is the thing all the wires connect to from the amps, radio module, phone module, Nav unit, DVD and CD players. That unit controls the whole entertainment system. If the screen at least lights up and can display the ride height, average MPGs and stuff like that then the TSD is fine, your issue is elsewhere.

 

Thanks for your insight! Yes my TSD work just fine when it’s powered on so I don’t think that is the issue. After bypassing the Nokia unit, I’m left with the amp, tuner module, CD player and nav unit to check. But the question is how do I evaluate them as being problematic?

 

When you bypassed the Nokia unit did you plug in the plastic bypass plug to keep the circuit complete? Your fault does sound like the Bluetooth module is at fault but if you simply unplug you end up with a broken circuit which gives the flashing orange button and screen crash.
I also found my sat nav unit was draining my battery overnight which could be the cause of your battery issues.

I had the 'Can Bootloader' message on my 2005 and found the fix. Sounds like a different problem than the OP from 8 years ago, but just adding to the knowledge base.

HLDF CAN Bootloader Waiting for download.....message on Nav

If anyone has a recovery DVD I would be most appreciative. LR part YIA500010 I believe. My nav screen is stuck with the message HDLF CAN waiting....message and stuck on a Spanish Christian talk radio station. Did the Bluetooth bypass thing, disconnected the battery, wait etc. Even bought a...

UPDATE!!

So I had my wife take the RR to an independent import shop and they hooked up the scanner to scan the system and found out that my bluetooth bypass was the issue! I basically had it wrong (rather my mechanic did) and/or did not properly bypass the unit. Additionally he noted that once he totally bypassed the bluetooth unit, he went into the system via the his scanner and disabled the bluetooth functionality and viola, the radio comes on and stays on!! Just wanted to share that solution for anyone else that may encounter this exact same issue and no you DO NOT have to replace the nokia unit if you dont care about the bluetooth functionality.

My next steps are to figure out how to add bluetooth streaming and phone connectivity (a local shop says it can) and also add a backup camera via this GVIF module (http://car-solutions.com/en/gvif-interface-for-lexus-toyota-land-rover-nissan-jaguar.php ) or the navtool interface. I have been reading horrible reviews on the navtool customer service and Im not liking what I am seeing so I may focus my attention towards the GVIF module as another user on here has used it successfully on a RR Sport to add a backup camera. Hopefully i can add a dvd player too but then again, sound interface may or may not be needed as there is NO AUX input on '05 RR. Stay tuned...
