Bluetooth problem!

Hi, I was able to pair my x1 to my pioneer headunit in my car and get the a2dp to work, but say when I leave the car and it d/c as it should, it does not automatically reconnect when i start the car again like it should, I have to manually go into the settings and set wireless stereo again. Anybody know a solution to this? I am used to my old phone just automatically connecting everytime I start the car. Phone is visible also.
Hi, can I ask how you get your pioneer unit to work with X1? I've tried pairing my Pioneer unit to my X1 and it doesn't connect. Btw, I want to use my unit for handsfree calling. Thanks.

BMW android Head Unit NO BLUETOOTH OUTPUT SETTINGS!

Hey all, i bought an android head unit for my bmw and want to pair it with the stock iDrive system so that I can stream everything from the android head unit to the stock system via bluetooth and not aux. Below is the issue i run into when trying to accomplish this.
I dont have a bluetooth section in the android settings. I was given a tip by someone to add a quick settings toggle widget for bluetooth and was able to get the bluetooth settings to come up. Once i did that i cant actually turn bluetooth on. I tap to turn on bluetooth and it doesnt turn on.
I am able to connect my phone to the unit to stream from my phone to the android head unit but thats it. It seems as though there is a bluetooth input but no bluetooth out.
Please help!!!
None of them do. its because it has the bluetooth input. Ive heard of people bricking their units trying to get it to pair for bluetooth output.

Android 12 Head-Unit (UIS8141E) bluetooth disconnects after a second

Hi, I have a head-unit with android 12 and I need to connect the car stereo bluetooth to them.
The problem is that disconnects every time I try to connect.
I do:
Reset bluetooth app
Unpair, pair etc etc
No setting for pairing mode in the head unit (passkey/numeric comparision).
Modified all options under deveolpers setting without luck.
I can connect phone or tablet (with a code), so I think that he cant pair with devices without screen.
is there anybody experiencing the same?
Edit: So I think that the headunit has a sink bluetooth and they can't send sound like the phone, is that correct?
What solution has this?

IDoing Headunit Bluetooth Issue

Just installed an idoing headunit on my 2019 WRX. Everything works great, but it seems to have issues saving my phone for Bluetooth. I can initally connect to my phone just fine, android auto wireless works great. But when I go to park my car for more than 10 minutes, it seems to lose my phone as a paired device. When this happens, it won't auto connect, and I have to click the "BT Reset" button in the bluetooth app settings to get my phone to show back up on the "Paired devices" list. Then I can connect to it. Whats weird is if I turn my car off and turn it back on within a couple of minutes, it doesn't lose my phone as a paired device and auto connects. Seems to happen when the car is parked and the head unit is off for more than 10 minutes. Anyone had this issue and have any tips? Thanks

Issues with bluetooth calling via Zlink Android Auto

I purchased ac8227l android head unit which came with Zlink 5 installed which supports wireless carplay and Android Auto.
It connects just fine but the problem is with calls. As soon as Android Auto is connected, the bluetooth disconnects and the Android Auto only works through the WiFi hotspot that is created by the headunit.
Now the problem is, when I try to make a call or receive a call, the call is routed to my phone's earpiece because bluetooth is not connected.
I tried with wired Android Auto but had the same problem.
I also tried to go into bluetooth settings and manually force connect bluetooth but I get an error saying "Wireless Zlink mode now! Connect bt not permitted". I get this error even with wired connection for some reason.
My Zlink version is 5.3.5 and Android version is 11.
Hello
I have the same problem. My device is AC8257 based.
But contrary to your situation, i can re-establish the Bluetooth manually.
Another issue, the icons are very small and Google assistant does not listen to my voice.
In carplay mode, everything works fine.
