W221 ANDROID touchscreen...
The same factory menu allowed me to update the "Music" application - so now I have a quick way to run Zlink by selecting Music (I play music from my phone anyways).
As for the audio quality - I would say it is identical to what it used to be. Of course, there is a noticeable difference between playing OE DVD / HDD and AUX line in, so if you can live with AUX-in quality - this is pretty much the same.

All NTG4x and newer settings result in a black screen. When trying with NTG 3.5 options (19 or 20), I get distorted view like this:
One thing I noticed is that you need to be super careful when scrolling through these FACTORY settings because it is super easy to set things wrong (when scrolling you can actually press something). Like... I somehow broke the knob functions (then I learnt I need to set to type B), then also I managed to configure it so that when you select AUX in the source, it automagically turns the Android screen on (you don't need to tap it). This is cool, actually!
//EDIT: Aux Switching Mode --> Automatic does the job. Cool!

How's the quality of the plastic bezel and hardware? I'd hate to find it's got some cheesy looking cheap plastic, doesn't fit quite right, or rattles around. The car may be old, but it is an S-class after all.




That being said, here are my observations for the Android 10 version:
- Definitely go for the faster processor and higher res screen. Prices are the same. You should be paying around 450-500 shipped DHL from one of the big vendors.
- Harness is improved, including having fixed the issue with the AUX wiring we rain into on this thread.
- They now don't ship the AUX box anymore as it was useless. TV box still in the mix if your car has TV.
- The bluetooth stack is totally f-ed up. That means you can't use their phone app for bluetooth and use other devices at the same time like OBD dongles or anything else. There is a workaround which basically means you either use one or the other.
- The built in carplay has software issues. I got it to work once but never again. The external one I was using with the Android 8 unit still works fine.
- Sound is better with the built in DSP.
If you are on Android 8...should you upgrade? Not really...not until the software issues are fixed. You're not getting anything ground breaking to justify the upgrade.
These guys here did a good job keeping track of all the issues and the latest firmware. You can install the UI files, as they are the same, but not the MCU files. All explained here: https://f30.bimmerpost.com/forums/sh....php?t=1699764.
I originally just had the M-B Bluetooth adapter (the "puck"). Cell phone calls, and that was it -- no other BT capability. Then I installed one of the little $12 Chinese BT dongles that connects to the AUX input. That works great for audio to the AUX input, but doesn't integrate with the car's phone "awareness". The phone sees two separate BT devices -- the M-B puck, and the new dongle. It works great. I can hear my streaming music, Waze directions, all of that stuff -- and phone calls are handled seamlessly, muting the other audio during the call. It even lets me use say Siri while driving down the road for completely hands-free operation. No button pushing at all, I just say, "Hey Diri" and it works. The phone will read my text messages to me, send replies, etc. Now that I think about it, I haven't tried just removing the M-B puck to see if it all works without it. That would be acceptable, as all I'd lose would be the use of the dial pad on the center arm rest or dialing through the COMAND screen, two things I can definitely live without.
I don't care about OBD devices, but I do care about the above -- streaming music, nav directions, making phone calls, reading and sending text messages without needing to screw with the phone while driving. How well (or poorly) do those functions work?
And if Car Play doesn't work, I'd think that would be a pretty big defect... but I don't know, I've never actually been in a vehicle that has it, so I've never used it.

All these units mess with the standard implementation of Android bluetooth, to make their custom dialer apps work better supposedly. Long story short they have no idea what they're doing and mess up Bluetooth many times. So you really can't pair anything bluetooth like you would with normal Android. You have to go through their dialer app to pair your phone...There are workarounds though to pair anything. In this particular version of the firmware, 2.3.0 there are a few bluetooth issues:
- Problem pairing phones with their dialer app and getting the built in wireless carplay to work
- Problems pairing other devices (anything but a phone) using the standard Android pairing process
- Their bluetooth (phone dialer) app completely cuts access to bluetooth for any other app
- Bluetooth defaults to OFF every time the unit boots (probably to prevent other apps to use BT before their dialer app starts)
Workarounds so far:
- Disable BT in the factory config (so their crappy app never starts)
- Root the unit
- User tasker to turn on BT on boot
- Pair your devices with apps like nRFConnect
- Use external carplay.or MB Puck for BT calls.
I am sure it will be fixed in a newer firmware as the older Android 8 Firmware worked fine and none of these issues existed. I have also extracted their BT app and will take a close look at what they're doing when I have some time. I am sure it can be fixed if they decide not to tackle it. This is a big issue for me as all my external stuff (to control ambient lighting, CAN, LIN, etc is on BLE).
Unit itself works quite well, but should the built-in carplay work only with wifi or does it need the BT as well? Like Megacrazy stated, the custom dialler is total bs.

The carplay needs both bluetooth and wifi unfortunately....BT to pair and wifi to actually work.
I was wondering should I buy another ashtray, break it and install a wireless charging mat, but might as well skip the mat and buy a wired carplay instead if the BT pairing starts bugging enough.
while browsing and googling, there are two different opinions, system uses its own gps antenna and shares it with the phone, or system uses iPhone’s gps. Which one is it, and has anyone else had this problem? Seems that it’s common with Jeep head units. Software glitch?
I’m using iPhone X with the latest IOS.
Going to try this next. Maybe it helps, maybe not.
1/ audio quality - much higher when streaming things via bluetooth than when using Android Auto (e.g. playing spotify using AA native app). Built-in phone dialer app working to play music over Bluetooth does seem to have a much louder signal...
the only reason I noticed that is because of problem number 2): sometimes I am unable to play anything that originates from my phone - music stops after 1 second. I hit play, it stops after a second. No matter which method is used - be it bluetooth audio stream or Android Auto Spotify. Disconnecting the cable (disabling AA) and reverting to Bluetooth only streaming solves it (but I loose the carplay/AA experience). And this is totally random - most of the time it just works fine.
So yeah... expectations from this unit are high, but there is still a lot to be done.

In terms of audio quality, try installing a USB DAC/sound card. Apparently it improves sound quality a lot. I have one on order and I’ll report findings. It’s been covered in the BMW forums link I posted earlier.
But I can confirm that the same issue is with carplay, unit stops playing music randomly.
Edit: Btw, how often these units get a new update?

Also, the latest Q OS version 2.3.0 fixed the issue with audio quality problem I had (difference between BT and AA) - it is perfectly loud and clear now
M E G A H A P P Y !!!!Teasers:
One minor inconvenience (last, I promise!) is that I need to tap the screen for the knob to start working over the segment with controls - but I bet I can solve it directly with Headunit Reloaded app owner!

Ofc I was naive to assume that the unit is loaded with the newest firmware, and surprise, it wasn't. Will try to update from 2.0.9 to the newest 2.3.0 and see what happens.

Was all of your problems solved, missing pixels from the left side of the screen when in NTG mode as well?
