I tried unplugging the battery and it didn't work, I have the same issue, Bluetooth is grayed out and I can't even reset to factory default settings.

I do agree, it sounds like hardware, I had the 1.08 firmware and upgraded to 1.09 and that didn't fix the issue... it is very frustrating, I did every single thing I could and nothing solved the issue.

Carl82,

 

I am having the exact issues.  The bluethooth button is grayed out and when I try to pair to the radio I get Error - 02.  Unfortunately my radio is not under warrenty and Pioneer want $80 just to look at it.  Did you ever get your issue resolved?  Am I looking at having to upgrade to a new radio?  Any info would be greatly appreciated.

Hey,

I still didn't fix the problem, I am still under warranty but I haven't got time to actually go to Pioneer and get this fixed.

However, I read online that unplugging the unit for 10 minutes to 1 hour would probably fix the issue, I will try that this weekend (or just unplug the battery).

Feel free to try that and post an update, hopefully that works and I save the trouble of taking the unit, going to pioneer, waiting X weeks until they finally fix it, etc.

I can't even reset the head unit to the factory settings, it gives me an error when I try to do it, I assume there is something wrong with the software.

Quick question..by any chance you running OS9 beta? The reason I ask is because I had the same issues as you describe with mines and once I reverted back to IOS8.4.1 my Bluetooth issues went away.. So I chalk it up to a glitch on ios9..

Hey,

Thanks for the reply, I am running iOS 8.4.1 but the problem is not related to my phone itself, is the head unit that the bluetooth is grayed out and I can't even reset the factory settings because it gives "error" while trying to do it, so it won't work with any phone or device. So I can't even get to the setting to pair the phone or anything. A few days ago I tried connecting the phone using carplay and after disconnecting it, for some reason, the bluetooth option went back to normal in the headunit and everything was working (without me having to pair the phone again or anything) until I turned it off again.

It is a weird problem that came out of the blue and I can't seem to find a solution, I tried researching a lot online and did all I could but without any luck.

Hello guys,

I have a Pioneer AVH-4000 NEX installed since February this year and no issues at all until now.

5 days ago I received a phone call while driving and I notice that the Bluetooth of my car is not working, I didn't pay much attention and just turned off the car and turn on again so the unit goes completely off and then on again and the Bluetooth is back without issues.

Now, since 2 days ago, I have the same issue and doesn't seem to work again, the bluetooth icon is grayed out and after a few minute, the button from the menu is available but everything inside the bluetooth menu is grayed out except for reset the bluetooth settings (which gives an error if I click it)

I tried:

1- Resetting the unit with the bottom right button using a clip (this didn't fix the issue)

2- I had the firmware 1.08 so I updated to 1.09 (firmware was done successfully but this didn't fix the issue)

3- I tried connecting the phone to use carplay, the first time after disconnecting the phone, the bluetooth came back and was working without issues until I turn off the car and now the bluetooth doesn't work anymore.

4- I have a bypass, I tried using a dvd movie and it works perfectly fine (just in case the bypass was not working properly, I assume that if the dvd movie plays then the bypass is fine)

When I go to Firmware Information it shows the firmware, the device number but the bluetooth firmware is blank. (when I tried number 3. using carplay, unplug, bluetooth worked temporarily), the bluetooth firmware version showed HW01-SW03.21.30).

There is an option to reset the unit to factory settings, if I click there it gives me "ERROR", same with resetting the bluetooth options, it gives me "ERROR"

If I switch to the Bluetooth option (to listen music using bluetooth) it gives me ERROR-02.

I called Pioneer, they say that I have to bring the unit, I just want to see if there is something that I can try before going that path, the unit is still under warranty but is mostly the pain of potentially be without the unit for 1 month. (if they have to order a part)

Everything else works perfectly fine, carplay, SD card, DVD movies, no issues at all except for the bluetooth. I didn't do anything, it just stopped working out of the blue.

I really appreciate all the help that can be provided.
