Have you tried bluetooth calling?

I received a call last night, and although I was able to hear, the caller did not seem to hear me until I disabled bluetooth. I will test it out further... When I was using RCA, buetooth worked well, even with Whatsapp.

I watched both of your videos, and I tried what you recommended by dropping the eq level to 1/4, but I did not like the way it sounded so I took it back to default.

Lowering the master volume on the DSR-1 allows you to adjust the gain in case it is very loud.

I was able to lower the DSR-1 Master volume, it is currently at 85% at -7.8db, the subwoofer volume is also at 85% (-3.0db), and the punch eq volume is at 50% (9.0db).

The nice thing about the DSR-1 is that you can import someone else setting through the app.

Concerning the punch volume knob:

My intention was to use it for the main volume, but since I found out that my steering wheel control works with the main volume with the digital out, I thought I did not need it anymore.

My Sub is being powered by a pioneer mono amp ( Pioneer Gm-D9601 2,400-Watt Class D Mono Amp ), which has its own volume knob, that is the one I use to adjust the bass on my sub.

I will try the tidal app you recommended.

No need for Viper4Android IMHO if using a DSP, the hardware DSP is much better.

SPDIF is 2.0, the DSR-1 has 2 extra RCA cable for the SUB, this way you can do the freq adjustment on DSR-1 .

2nd option: Most amp have a RCA out where you can connect your SUB.

I wasn't able to fully test the call quality, but when I received a call, I could hear the other party clearly, only issue they were not able to hear me, I did not plug in the external mic, i am using the integrated mic on the head unit itself.

The only issue is that you will have to lower the bluetooth volume in the joying setting, because the call is played on all 4 speakers, instead of just the driver's side when I was using the RCA out.

I have experienced wifi dropouts, but I wasn't sure if it was my phone turning off hotspot or not. Will have to further test.

The dashcam they sell on their site works pretty good and the quality is awesome. You may experienced issue if you use other dashcam.

Backup camera is good through RCA, depends on the video quality of your backup camera.

No head unit is perfect, especially true for these android head unit. Joying is by far ahead of the competition when it comes to these chinese head unit, they constantly improve their product and have a good customer service. One thing about these android head unit is the software is sometimes buggy, and they do not spend the time to test it out before releasing it, that's why we have forum like these. Sometimes, you will experience crashes, and othertimes you will find out you cannot install certain apps. But for what it is, it is pretty good, listening to music, streaming and navigation are the main components.

I also also experienced some usb issues, when when I start the car, I have to unplug my USB stick and plug it again for it to recognize it. It is a 64B USB 3.0 and I have it formated to FAT32.

I also experienced issue when using an SD car, as long as the unit does not reboot it is all good, but as soon I reboot the unit, it will not see the SD car anymore. I have to remove it and reformat it. I am using a high quality SD card from samsung, and I tried both fat32 and extfat formatted on my windows pc. The unit does not give you the option to format a usb or sd card.
