Hello,

Everything had been working great with my x920bt until I updated the firmware. Now my Bluetooth no longer works. Under Bluetooth settings, everything is grayed out except for 'firmware update,' which shows the version as blank. Under the service information screen the bluetooth version is '-----------'.

I have called Pioneer customer support and they had me try resetting user settings. When that didn’t work, they told me that the install was corrupt and to remove the unit and send it in to them for repairs. I am really trying to avoid having to go through all of the effort of having to uninstall the unit and not having it for a few weeks.

1. Is it possible to find and update the bluetooth firmware individually? If so, where and how?

2. Is there a way to reinstall the update (AVICZ110)?

3. Is it possible to restore to an earlier point?

4. Any other ideas/suggestions?

Thank you for any help that you may be able to provide.

You can download the BT Firmware from Pioneer's website.

I have looked extensively but am unable to find the bt firmware on Pioneer's website. The only bt firmware update I was able to find is for the f-series. Could you recommend a specific file to look for?

I think that there was a miscommunication. Unless I am missing something, I did not think that I could re-install the unit's firmware update as my system already has application version 2.003. What I am looking for is the bluetooth firmware only as it shows as missing (see photo). Is it a possiblity to only find and re-install the firmware for only the bluetooth? I have unsuccessfully tried to re-install AVICZ110. Is there is a trick to get it to re-install?

Thank you again.

Go to:

Firmware update

With the SD card in.

The 'firmware update' button is grayed out when I have the AVICZ110 on the card. I did also format the card and put on CNSD-110FM-SD2 and the button was not grayed out. When I did proceed with the update however, it gave an error after about 10 minutes of trying to update. I tried twice with no luck. Any ideas?

Thanks again for any help.

I have the same problem, except I upgraded my firmware months ago and now all of a sudden ,out of the blue the bluetooth stopped working and it is not showing any bluetooth firmware, I also tried to reinstall the 2.003 firmware from the same micro SD card I used for both my 920 units and it will not do anything , Called pioneer and they say to send it in ? This may be and end with pioneer products, very unhappy consumer. It should be no problem to reinstall, but then again it should have never just disappeared. Any other thoughts

Don't blame me or Pioneer if this bricks your bluetooth, as this is intended for the Z120. Do this at your own risk.

Step1: Extract BT_FW_3_10_2.zip

onto the root directory of your SD card. It should create a folder named "Firmware"

Step2: Boot up your AVIC-Z110 and press Home-Settings-Bluetooth Settings -

Firmware Update

Step3: After the 3_10_2 is complete, extract BT_FW_3_11_2.zip

onto the root directory of your SD card. It should create a folder named "Firmware"

Step4: Boot up your AVIC-Z110 and press Home-Settings-Bluetooth Settings -

Firmware Update

The update will take about 4 minutes.

Well, I gave it a shot but received the same message: "an error has occurred. The update has failed." Unless there are any other thoughts/suggestions, I guess my only option is to uninstall the unit and send it in to Pioneer. Thank you again for all of your help.

Yeah, I'm out of ideas, unless you want to wait for the X930 software to come out.

Why are you trying to install Z series firmware to an X series unit?

EDIT: NM - I see it's the same file AVICZ110.zip on their site.

Skikab, did you send your unit in to Pioneer, or did you ever find a way to get the bluetooth to work again? I have been having the same problem for months now, and I finally decided to call Pioneer Customer Service. They said that the bluetooth chip is broken, and that it's unrelated to the firmware update. Who knows if that's entirely true, but I'm sending my unit in. I can update you in 3 weeks...

Hey guys, was a lurker while scouting the unit before the x920bt (x910bt?). Anyhow, took the plunge last summer on the 920 and had a mostly flawless installation including the bypass. Anyhow, my BT disappeared over time. At first it only happened after my car was left in the 100 degree heat for awhile. I'd get in and boom, my phone wouldn't pair. I figured, ok, doesn't like to be cooked in the sun. No problem, it didn't happen that often. Eventually, a few weeks ago, it stopped pairing all the time.

When I called support, the guy was pretty direct and not sympathetic, but took me through a few troubleshooting steps and when we got to 'connection status' in the 'nav settings' he wanted me to engage and release the parking brake and report on whether the status switched from off to on. Obviously it wouldn't as I've already admitted I'd done the bypass. Not being able to admit that to him though, we ended the call with his advising me to have the installation checked.

From what I could get from him, there was not anything necessarily wrong with the bluetooth. It was just listed as being 'off' in the bluetooth settings page. I was unable to access these greyed out buttons, because the deck uses some kind of switch (can't remember what he called it) that made these (and other, I imagine) menu options available when the deck detected the parking brake being set. The fact that the deck reported the brake as being 'on' wasn't enough to make the settings available.

So, was this BS from a pioneer support guy trained to identify a bypassed (and thus warranty voided) deck quickly? or is this real? Either way, I would suppose that the next step would be to "un-bypass" the unit so that I had stock brake action going on and then go to bluetooth settings and switch BT back on.

Thoughts?

PS: I posted this under BT gone after firmware update even though I lost mine prior to updating firmware. It should also be noted that I updated the firmware this evening as an option of trying to trick the BT back on. Initially, it looked like that had worked, but eventually the BT shut back off on the page reporting it's on/off status.

Racer-X, I tried firmware stuff and experienced the same thing you went through where it looked like the BT was working, but then shut off after a bit. The Pioneer rep I spoke to didn't ask me anything like that. I told him that the Bluetooth Firmware version was all dashes like the OP mentioned, and he knew that the unit was messed up and told me to send it in. Hopefully your unit is still under warranty, but if it is, you should try calling them again and mentioning the Bluetooth Firmware version. Pioneer ended up sending me a refurbished one instead of fixing my old unit, and it seems to be working OK. The thing is that it will only pair with my phone, and not my wife's phone. Still, I guess it's better than no BT at all...

Thank you, I'll look into that.

Yeah, I just tried all of these options previously listed and no help. Please let me know if there are any NEW ideas that have developed over time as i see this topic is now almost 2 years old. I currently have this problem and it just started for me. I bought the unit when it 1st came out. (whatever year that was)

Many thanks,

Shaun

I tried to do the f/w update but since I had already done that years ago it did nothing but the f/w version for the BT now showed.  I did a factory reset in the system settings window and my BT started working again but had lost all remembered devices.  No big deal because the cause of this in the first place was wanting to pair my new Galaxy S4 with my Pioneer x920bt.  All is good now.

I was reading through this post because my AVIC-x920Bt is having the same Bluetooth Problems and the Map update on Pirate Bay doesnt seem to exist anymore.As  for the BT file...I was  wondering if installing the second file would work since this model came with version 3.11 installed...Any Ideas??

I would like to bump this thread. I recently deleted the prg0 and prg1 files and replaced them with the 2.03 files downloaded from Pioneer's website.

The unit has since stopped rebooting at the splash screen (which is amazing, thx for the info!)

The gps works, and finds a signal fine.. all other aspects of the radio work fine.

If i check my settings there is no firmware version listed for the bluetooth. I tried using the two update files listed earlier in this thread but it always gave me an error after 5-10 minutes of waiting.

I tried running a legit update off an SD card but my radio doesnt "automatically start the update process" as stated on pioneer's website.

Any info on how to fix this would be great, Ive made a lot of progress on this radio since finding your site.. so thanks!

Currently have the power and 12v start wire connected to a power source.
Currently have the parking break wired into the ground wire.. connected to a ground on the power source.

Am I missing some sort of wiring fix or is this strictly a firmware issue? Once again, thx for all the knowledge so far!

Im having this same problem with my 4000 NEX!

DONT KNOW IF ITS A SOFTWARE OR HARDWARE ISSUE

Thank you Sir.

This worked for me. This morning my Bluetooth, while I was streaming music, randomly just stopped, and then the Bluetooth was literally inoperable. Have been using the system for about 2 years with no problems and randomly the Bluetooth part of it just stopped working. Same symptoms as others, options greyed out, firmware showing '------', etc. 

I have already done the application update manually before, so didn't bother with that but the Bluetooth firmware files you posted were perfect. I did the first update initially, and the Bluetooth actually started working at this point already for me, but I did the second one anyway. Both updates took about 5 minutes.

Ok witnessed another problem after this above method which helped me.

It seems that everytime I turn the bluetooth off, the bluetooth software gets screwed up. When turning bluetooth off the the bluetooth settings menu on the unit, the bluetooth turns off but cannot be turned on again. When you try it just kind of keeps loading then sometimes I end up in the same state I was with the previous issue where things are blanked out.

Fortunately, the software/firmware update still works after. This software is very ropey, so a heads up for anyone else with same problem.

You followed the instructions of a 5 yr old post and loaded BT v3.11? What headunit do you have? Z110, Z120, Z130, Z140? What app/map version are you running? I believe the current BT is v3.32. It comes with the 2015 map upgrade.

Where can you find this combo 2015 map / Bluetooth upgrade?  And do you know if it kills the voice recognition features of the x920bt headunit?  I seem to remember reading that a certain upgrade killed the VR system, which I use frequently, but have finally been hit by the dreaded "greyed out Bluetooth menus" problem.  The unit has been bypassed, so sending into Pioneer would be useless and expensive
