I have a T-Mobile MyTouch4G running Android V2.2 that I am trying to connect to the AVIC-Z120BT. From the head unit I run through registration sequence then enter 4-digit pass code on phone. Phone connects then asks if I want to allow head unit to import (read) phonebook entries. I enter "yes" or "ok". The phone connects for a few seconds, then immediately disconnnects with the message, "Disconnecting from headset". Why doesn't it stay connected? Any help is greatly appreciated. Of course, Pioneer says there is no problem with head unit and T-Mobile says phone works fine. Stinks!

Does it still upload the phonebook?

On some phones you have to make your phone "Visible" in order to connect via BT.....I understand you are connecting and then getting disconnected but always make sure it's visible.

I found out the phone's bluetooth is defective so T-mobile is sending a new one. We tested another MyTouch 4g and it connected flawlessly. A G2 worked as well. Thanks for your responses. I appreciate it.

I have the exact same issue with the same phone. I also had an HTC Desire with the same issue. I thought it was a problem with HTC phones Bluetooth connection with this unit?? I called T-Mobile and they never gave me the option of returning the phone. Extremely annoying to have this type of head unit and not be able to have it work through the bluetooth connection??

Have you tried playing audio (mp3s or streamng) over BT after pairing? The reason I ask is I see the "disconnecting headset" message on the AVIC after pairing my HTC HD2 (running Android 2.2). But when I switch the AVIC to BT audio source, it connects and re-directs whatever is playing on the phone to the HU. It takes a few seconds to negotiate. So, I thing the disconnection headset message might be becasue the audio source is not BT.

My phone also works fine for incoming and outgoing calls over BT. BTW, my phone is running the OS off a Desire HD.

I think I have a defective phone, I tried my wifes mytouch and it worked fine. I will be calling T mobile about it in the morning.

VBlue42, it does not upload the phone book. It never prompted for that. I received a replacement phone from T-Mobile and it connects via BT, but when I make a call, it dials the number then immediately disconnects. it does this consistently. I am going back to T-Mobile.

You set the phone to Visible when connecting for the first time. After that it shouldn't be necessary to "Make Visible" any more. I did it once with my G2 and have never needed to do it again. Thanks for suggestion.

i am also having this kind of trouble for my rooted htc evo. neither audio nor headset work. headset worked once where i could only dial but hasn't work ever since. is it my phone or is it the radio. It doesn make since to have this radio if it does not have bt like it says it its name.

Hello,

Im running Android 2.2 non-rooted on an HTC EVO. It connects with the Z120BT and transferred my phone book over without major problems. Only problem was connecting took trial and error about 4 or 5 times. And transferred my ENTIRE phone book which I didn't exactly want. But anyways, how do I play music via bluetooth using the phone? I pressed "connect" on the head unit and it says use your mobile device etc. So I went to the Music App and played music but it wouldn't connect. I tried to send the mp3 over via bluetooth and a got a failed message on my phone saying Pioneer NAVI didn't accept. Lol. If anyone could help, i'd greatly appreciate it. Thanks in advance.

So, I have a Samsung Galaxy S (ATT Captivate) running Android 2.2 and I can get the two to recognize each other but right after that they connect and disconnect and I can't get the AVIC to recognize the phone as a handsfree device...only an audio device.

Any suggestions?

On the EVO. This is how I did it. Settings > Wireless and Networks > Bluetooth Settings

You should see "Bluetooth Devices" and under that it should say "PIONEER NAVI" or something of that nature assuming your devices are already paired.

Long hold "PIONEER NAVI" and another menu comes up.

There should be an "OPTIONS" button.

Both "PHONE" and "MEDIA" should be checked.

If they aren't both checked. Check "MEDIA" first. Try to see if it will play via bluetooth using the stock Music Player app, Pandora or Double Twist. The stock music app, Pandora or Double Twist will play and you will have the ability to using steering wheel controls to some degree. However, you will not see the name of the song, artist, album art, etc on the headunit.

On the Headunit, under "Bluetooth Settings" through a series of menus find the device you want to connect (if more than one phone) under "Select Profile" there should be an option to choose "Handsfree and Audio"

During the processes of connecting either audio or handfree as one person mentioned, make sure your phone is "Discoverable" or "Visible".

Hope this helps.

The way I fixed it was by resetting my phone

Yes THANK u, ive been looking for this thread for QUITE a while now, I have:

Android EVO 4g with Sprint

& Avic-z110bt upgraded to z120bt w/ BT firmware 2.11

I have this same exact issue, and "c12rack's" response on 12 feb 2011 did help some, and took me a couple steps forward with my issue, i still have no media connection streaming Youtube vids and playing music ALTHOUGH it says on the phone that I am connected by Media & Phone Audio. On the Avic i go to Source>BT and it says its disconnected but then on Settings>BT i have the EVO connected by what appears to be both as well. Ive tried disconnecting, unpairing, rebooting phone, changing PW, changing device name, erasing all registered devices on avic and still no luck. Take note that it use to work perfectly before the firmware update, but dont quote me on that because it could be a phone update that took place for my phone as well. Is BT firmware 2.11 the latest?? if not please redirect me, and if thats not the case please assist, or at least AGREE with me ANDROID USERS!!!! LOL

I have a Sprint Epic (Samsung Galaxy S) and BT support is spotty as hell. I also have a Blueant Q2 that does audio streaming and it works flawlessly. My conclusion is that Bluetooth support in the Avic is every bit as half-assed as every other feature in this half-assed head unit.

To connect I have to pair and register, then connect to the audio gateway - sometimes manually. After a phone call, the phone portion will be dropped and can't reconnect until I reboot the phone.

I'm sad as hell that there isn't much of a hacking scene with this head unit because the hardware appears to be decent but it doesn't do a single thing half as well as my phone which was a third the price. I'm so glad that this came with the truck I bought because if I'd used my own money I would have set this thing on fire and thrown it through a window at Pioneer's headquarters.

VERY big android modder here....

On some of the phones pay VERY close attention to your status bar as you connect, sometimes you'll get the Triangle with an "!" mark in the middle.. QUICKLY slide your status bar down and click that then click "Allow" Some of the firmwares for Sprint, TMO and Verizon wont allow the connection due to security issues (people can steal the info via bluetooth if they connect to you, automatically and send the req code).

Was testing this theory in the local bestbuy with 3 different phones on the 930bt, 3300bt and 130bt

Stock phones I had to do it, but on my modded droidx it went without a hitch

EVO 4G here. I haven't noticed a status bar in the BT settings menu. Is there one on this phone somewhere else? I can't get my contacts transferred to my Z130.

I just tried to transfer 1 contact from the phone and I do notice, in my notifications window, the triangle with the "!" in the middle. The explanation the phone gives is that the target device, Z130, does not allow this type of action.

I have a EVO 4G and i had some weird BT connection issues as well. However it was only after upgrading to Sprint's Version of Gingerbread. I here are the problems I had and what i had to do to fix them.

1) Phone would connect but couldn't transfer Contact or sync PhoneBook. After pairing my EVO would pop up a message asking that the "Pioneer unit is asking to sync phonebook" I would click 'Always Allow' and nothing would happen. To fix this I had to delete the bluetooth pairing on the Z120. To do this i had to "reset to factory defaults. I also deleted the pairing on my phone. Then I paired them back up and my contacts would sync.

2) When I would go to bluetooth Audio to stream it would play through the pioneer unit for a few seconds then drop connection.

To fix this i went into the Blue tooth settings on the unit and choose the connections option, I think it's the first one with the phone name. After it gave me a message about disconnecting the phone you'll see the list of the different ways it will connect I choose the first one that's handsfree and Audio ( can't remember the names on the list). After that it reconnected and i was able to stream audio w/o it loosing connection every couple seconds and My contacts still worked.

I have a Samsung Fascinate on VZW w/ 2.2.2 (Froyo)

When it was updated to Froyo, I had issues w/ the VOBT as it stopped working and would only sync for audio and not the phone.

This was a known issue.

I tried resetting, re-pairing etc.. nothing until,

There was a recent patch (ED05) that fixed that and VOBT works 100% now. Including Phonebook syncs.

Check for patches and updates, look for other users on android forums having the same issues but most of all, speak up!
