Eunavi RK3399 STM32 DSP lack of bass problem - Android Head-Units

Hello! I've just got Eunavi for my BMW E39 and I'm experiencing very low bass. The device is as following:
Android Version: 10
Hardware Information: RK3399 - ROM 64GB - LPDDR4 4GB - 1024X600
CPU: 8 Core (Quad Cortex - [email protected] Quad Cortex - [email protected])
Kernel Version: Linux 4.4.167+ - Thu Aug 6 16:04:11 CST 2020
OS Version: KC1E0130-P01-11.1.4.8.1 - BLINK161 - 20200806 - N3
MCU: STM32 - 20200721 - 11 - KC6 - 40
The device works pretty good, except the following issues... There is almost no bass on whichever type of music it plays. Bluetooth, radio, youtube... Everything is flat at sounds terrible. DSP settings (EQ) helps a bit, but still very poor flat sound, much worse then my old android non-dsp unit... Then I discovered the settings screen for DELAY and I tried setting rear speaker values to more then 200 and BAM... Great and very clear bass is there... But whenever device resets, it loses the settings Actually it visually shows as its still set to previously selected value, but the effect of the value is not applies, up until I try to re-set the value again (playing around with the value restores the bass immediately)... Any ideas on how could I solve this, to avoid having to play around with the settings each time I start the car ?????????

Hi there,
i have a similar HU
Tristan Auron
BT2D7018A
MTCE_LM_V3.06_1
Cortex A35 Quad-Core / Rockchip PX30 with 2GB-RAM
Does the PX30 fast and reliable? What if compare to RK3188/PX3/PX5?
@ this Moment I think he PX30 is a light Version with only 4 cores of the PX5.
Compare both chips, the PX30 is more for Multimedia and have 15% less Power and no 4K Support.
The Temptetures on my Unit reaches 65°C after 30-40 minutes max. Average Temperature is about 48-55°C without coolling Mod.
My Unit-Software is not pure Android, so the Performance of my Head-Unit has only 2GB of Ram and that’s the biggest Problem.
Opening 5-6 Apps is good at all, but start to enter an Address to Google Maps so I see micro Stuttering when the Unit loads the Route.
On Travel the Unit works well with Music, Navigation and Speedalert running in Background.
I think the CPU is good enough but yet there’s no Custom-Rom for better Experience.
Greetings Dimes

Either it is a head unit Systems setting, or it is in your Settings -> User -> Locales (or regional settings or whatever it is called)

Android Head Unit T5 - Fiat 500x

Hello, I hope this is a good place for the topic I am opening. To get started, I need your advice on how to set up my new T5 head unit properly.
I bought this device online and according to the specification it should have 4 GB / 32 GB of memory. It turned out that the device was modified to show that it has 4 GB but actually only 2 GB and instead of Android 11 the device is actually Android 10. Quite a common scam committed by sellers from China. To cut a long story short, after a dispute with the seller, half of the amount was returned to me. My car is a Fiat 500x and originally the device was set up to use the CANBUS protocol for the FAIT Doblo car. There was no FIAT 500x on the list. Some car settings were not available to me with this FIAT / Doblo protocol so I found it to be a much better option if I use the JEEP - Renegade CANBUS protocol. With this new protocol, some previously disabled car adjustment options are now enabled for me, but I still miss seeing basic data on fuel consumption, mileage, etc ... The Air conditioning settings do NOT work either with this JEEP protocol.
Did any of you have experience with setting up a Fiat 500x car and do you know how to update the device so that in the end I have the original FAIT protocol for 500x.
Thank you all in advance.
