Nexus 4 4.2.2 and RNS 315 car system issues/tweaks

Hi,
I am a happy switchover to Nexus 4 from my iPhone, only thing I am starting to miss are some integration bits with my car audio system.
I am currently connecting the phone via bluetooth and it is working well, I can stream music and use built-in car dialler, however, I do not see what is currently playing on the car dash.
When I had the same setup using iPhone, I could see the currently playing song information. I can still skip to the next song using car's steering wheel buttons but I only see "Bluetooth audio" on the display.
I am using the default Google Play app to play music - have also tried with dogcatcher but no avail. On the iPhone various app worked - Music, Podcasts..
Second issue I have - is it possible to "force" phone calls to background when connected to bluetooth headset? I would quite prefer the satnav to stay on instead of seeing the current caller's information - as I already see that on my dash.
Thanks!

The first problem is caused by you and other people buying iPhone. You have contributed to pushing 3rd party manufacturers into supporting proprietary apple formats and communication protocols.
There is a perfectly fine Bluetooth protocol for track display, but your car stereo doesn't suport that, only the proprietary Apple one.
Hopefully you are now aware of the evil lock-in tactics that Apple have been engaging in, and next time you will check the product specifications to see see if your purchase is going to lock you in in any way.

Volkswagen and their bluetooth devices work fine with Android. It's Android that lacks a proper protocol to push that info to the radio. I know this because I worked with VW for months on troubleshooting the issue. Eventually, I obtained a stock galaxy S3 and it displays info just fine. With a custom 4.2.1/4.2.2 rom, it does not, just displays "BT-Audio".
CM is adding in bt tag support, but it currently doesn't work with play music, but is noted to work with pandora.
OP - your second issue is not possible. The radio automatically flips to the most recent info it has to display to you. You can manually toggle it back IIRC, as I can on mine.

I have the same issue:
See thread which explains a lot and could solve your issue:

We need to get AVRPC in our devices then it would work.
I drive an A5 SB with no go : ( to bad

yea the bluetooth works on my ford focus, but doesnt show the info of what track is playing.

H870 Bluetooth Issues with VW RNS 315

Hi,
I recently got my LG G6. I'm really satisfied with it. Especially the camera and the performance , but I have a problem with my hands-free equipment in my car .
Everytime I want to use the phone as audio source e.g. Spotify I would have to un-pair and pair the devices again .
I have a Volkswagen Passat 2014 with a RNS 315 and original hands-free equipment.
I can pair the devices without any problem. Also the "connected with audio equipment" option will be displayed on the phone. After a few seconds this option disappears in the overview of the connection details, only "use hands-free" and "sync phone book" will be displayed on the phone. Only in the overview of paired devices I can see that it is connected to the car as audio source. I can use the steering wheel buttons to switch between the tracks and the current title displays on the car radio.
The problem:
After the phone disconnects form the car (remove the key) and it reconnects gain (starting the car again) the phone do not recognize the A2DP protocol anymore and it just connects as hands-free without the ability to play music over the car speakers. I can use the steering wheel controls to switch the music title and the car also displays the current title, but the audio comes from the phone and not from the car speakers. But the car displays the phone as hands-free and audio source.
I had no problem with my Nexus 5X. I have already tried to clear the bluetooth cache and data. I have already tried with an other LG G6 and there was the same problem.
Is there any way to enforce A2DP even if the phone do not recognize it anymore?
The phone software is V11g-EUR-XX with security patch level 6th November 2017.
I hope anyone can help me, because I don't want to send it back.

Same issue here. I have to unpair and pair again if I want media playback to the car. I have tried pretty much every solution I came across and nothing worked apart from pairing again. Having said that, I think the problem is both with the RNS315 and the G6. I had a similar issue with the Note 3 but disconnecting and reconnecting was enough so I was using trigger to get around it. I have a small hope the oreo update may fix it.

Here's how to remove audio lag in carplay (sound, music and most importantly call lag) - requires Carlinkit dongle

Just posted the same on reddit:
Gonna be a long read, with many tips
So, I have an Android headunit and was using the built-in Carplay app Zlink. Now I'm using Carlinkit dongle for Carplay, and here's why.
I'm referring to Carlinkit wireless carplay dongle, not Carlinkit wired to wireless adapter - very important!
As you already know, using Carplay in Android headunits generally introduces some audio lag, especially on wireless carplay. For example it takes some time after you press "next song" until the current song stops and the next one starts. Same with pause. Especially with wireless Carplay.The biggest issue for me is during phone calls, when you ask a question, takes a while to get an answer, and you also end up talking over eachother.
This is what I did: In the recent versions of Autokit with a recent version of the box firmware there is an advanced option to route audio through car bluetooth instead of through box. (not sure exactly what version you need, but latest versions have this option)If you select this, you need to connect your phone to the headunit bluetooth also, not only to autokit's box bluetooth (you connect to box BT for wireless)
Doing this allows for all audio to go through headunit's bluetooth which is basically lag-free.
So my setup is like this:
Wired: phone is connected by USB to dongle, and by BT to unitWireless: phone connects to box BT then to box WiFi for Carplay, and meanwhile also connects to head unit's BT for audio.
Advantages:
- No more lag when switching music or making calls, even in wireless carplay mode
- When the unit detects a call, it might do something smart that you want. Mine has a different volume for in-call, so I can now have louder phone calls without manually changing volume
- Since the phone is playing music over the BT connection, the unit is now aware that music is playing and knows artist and track name and it might display it somewhere, maybe have an overlay when changing tracks. Might be nice if you switch outside Carplay to some other screen/app on the unit.
- No more lag
- If unit has proper echo cancellation, it should work better, as BT is better controlled by the unit, unlike Carplay solutions which can have various delays that the unit cannot counter easily.
- If you were using built-in Carplay before (like I was), you wouldn't be able to use wireless Carplay and have internet from a hotspot, since unit's wifi was busy. If you switch to using Carlinkit dongle with Autokit, you free up unit's wifi and can now use a hotspot.
- Did I mention no more lag?
Disadvantages:
- Seems to use more battery when in wireless carplay mode, I think BT is less power efficient. My unit has BT 4.0, if yours has BT 5.0 maybe this would be better.
- This is a minor annoyance, but if your headunit BT is slow to connect to the phone (mine is) and you start playing music as soon as you have Carplay working (or have autoplay enabled), you might have music coming out of the phone speaker(s) for a few seconds, until unit BT connects and music goes to BT.
Beware the following:
- When using BT to listen to music, the volume on the phone matters, so make sure to turn it up to max. This volume level will be saved separately from usual phone volume though, so it's not a problem.
- Latest version of Autokit didn't find box updates for me, so if this option is not in the advanced settings, you might need to revert to an older version and use that to update box, then update app.
- After making this setup and trying to make a call, you might not hear anything, as the phone might use the carplay connection instead of the bluetooth connection. Just switch output from the phone "audio" button, and it seems to remember it for next times.
- Depending on the headunit and the software, when you get a call with this setup, headunit might decide to switch to it's own bluetooth phone app or just show an overlay. If it switches and it bothers you, try to find a solution specific to your unit. If it's an overlay and you want to remove it, what worked for me was going into android settings for app permissions and removing permission to draw over other apps for the unit's bluetooth app.

thanks for your post; i have a carplay dongle connected to an android headunit; when i call someone they have a very annoying echo voice. i wish it improves when my phone it connect to headunit bluetooth for calls

Are you able to get navigation audio using this option? I have the same dongle and was hoping I would get navigation too but I only get music audio. If I say "Hey Siri" just before Waze/Google Maps is about to prompt then I can hear the audio but doesn't really help me when driving. Looks like in my car the Navigation audio is going over the Siri channel? Not sure if anyone has a work around for that. Could be the way my car has bluetooth setup -- it's a 2012.

Can you provide a link or exact model for the "Carlinkit wireless carplay dongle"?

What is your box version?
When I try audio routing, on my iPhone still it shows Carplay as sound output option.

I tried this same option, but when my iPhone connects to wireless CarPlay, the head unit (not the dongle) turn off the bluetooth automatically, anyone knows how to stop this?

Wait, What??? the only way to remove the 3 second lag from headunit with zlink is by buying a dongle ??? I paid extra for Carplay/Android Auto Headunit.
And the 3 seconds delay is driving me nuts. This happens even without the zlink app open.

The dongle is carlinkit Autokit (CPC200-CCPA)? It is specially made for Android head units.

TS10 CarPlay audio only plays through front speakers unless Google Assistant is activated

Hi all,
I recently purchased and installed an Android headunit for my Mitsubishi Lancer. So far, I have been very happy with the product.
However, I have come across one issue.
The headunit uses the T-Link app pre-installed to allow for wireless Apple CarPlay and Android Auto through Bluetooh and wireless - this works well. I use the spotify app to listen to music on Apple CarPlay, but when listening to music, all the sound only plays through the front 2 door speakers. This also means some songs are missing some pieces of music and everything just sounds compressed and stereo. This is until I activate the Google Assistant by pressing my steering wheel voice assistant button. When this activates and the headunit starts to use the microphone to listen to my voice, the music from spotify in Apple CarPlay can be heard through all the speakers and sounds like how it should - surround, not compressed, etc. Once I cancel Google Assistant the music returns back to just the front two speakers.
This issue doesn’t occur elsewhere on the Android headunit that I’ve discovered. For example, FM radio sounds normal and goes through all speakers.
I need some help fixing this. I have messaged the seller of the headunit for help but also wanted to post here in case the community could help too.
Thank you

Also to add to this - now Siri does not work. Attempting to get Siri to activate or read out a text causes CarPlay to freeze and the following message to appear (translated from Chinese):
"Sorry, the program "SpeedPlay" is abnormal and will be restarted soon"
before CarPlay (T Link) suddenly closes)
Really need some help on this one please!

Android Head-Unit Bluetooth Problem - Clone CarPlay Hardware

Hello.
I use an Android multimedia system in my vehicle. I bought this system online. A Chinese-made CarPlay system for vehicles that do not support CarPlay. I think it has some flaws because it is a system that has not been developed very carefully. This system came with a CarPlay clone application called QLink. Everything was going well, but when the phone call came in, things changed.
The system turns off the playing music and shows the incoming call. That's nice. When I answer the call, when the voice of the other person comes, the music that has been stopped starts playing again. Likewise, at a time when I have stopped the music in the car, if I turn on Siri, the stopped music starts to continue with the first beep of Siri. In short, every sound triggers other sounds that have stopped. I'm so tired of this situation. I disassembled the hardware. I couldn't find any port to connect to PC. I decided to tamper with the software.
There is a situation like this; my car has a bluetooth module and also the hardware i bought has its own bluetooth. But when I want to connect to this Android device via bluetooth, no option about sound is seen in the details. Only "contact list" and "internet sharing" options appear. Permissions such as "music" or "call" do not appear in the bluetooth options. I think it's because this "tablet" has access to the car's multimedia tools, but doesn't have any sound devices like microphones or speakers on its hardware. This is my guess of course. If a tablet does not have a microphone and speaker on it, then the sound-related permissions should not be visible when connected via bluetooth.
I want to bypass everything like QLink on this system and turn it into an Android tablet only. Then I will create a vehicle system as I want by installing my own applications. Here is the problem. While I understand electronics in general, I'm a total alien when it comes to mobile gadgets and Android. That's why I have a few questions for you and I will follow a path accordingly.
1- Can I fix this bluetooth audio permissions problem on tablet? With tricks like virtual microphone, speaker. Or is it something else other than my guess?
2- If I clean the tablet and connect directly via bluetooth, will the music and calls playing on the tablet play on the car speakers through the connections of this hardware to my vehicle? The service that installed the system brought the air conditioner, media and ECU connections of the vehicle together with a connector and connected them to this tablet. Will this link continue to work the way I want it to?
3- Did I explain my problem clearly? I dont know but if you need to know anything that I didn't mentioned then you can ask me every detail.
I really need every bit of information. Thank you so much for everyone's help so far. I'm looking forward to your answers.
