I had a PX5 unit in my bmw for a bit, then went back to my 10-year old pioneer. The sound, build, and component quality just wasn’t up to par to maximize the rest of my equipment.

That being said, there was nothing wrong with it and I did like the interface and apps a lot.

Find the appropriate threads on XDA forums, was a huge help for me, including custom firmware that improved sound quality a bit, and a custom rom that was more geared towards auto use with some helpful features.

Good luck!

 

Thanks Ali. I’m on the XDA fourm and I have picked up some info there but not much response to basic questions.
I'm very happy with the sound of this unit. I’m not using the stock DSP.

 

I used a tablet (samsung) for a while, and I totally loved Car Launcher Pro, the GUI is awesome and fully customizable, with launcher widget and system/thirdy part widget. You can also add more pages, I had one totally black with few info(speed, time, and a plain player) for the night when I didn't want it too much bright!

 

I've got a Joying Android 10.0 based unit sitting in a box waiting to be installed. Not sure if that's too much of a canned product for what you're looking for info on or not.
won't be able to contribute for a bit though as I'm putting in a new system and going to reduce variables by using my old deck until I'm ready to devote my whole attention to installing the Joying and learning how to use it. I will definitely be comparing my current high end deck analog output into Helix with the Joying SPDIF digital input as well as the various ways of feeding that digital iinput

 

I've been using a volsmart in my truck for a few years. It was one of the few that had a volume knob vs buttons which I really wanted. It's had a decent number of software bugs, the output is a bit noisy, and it has no built in DSP stuff. I wish I had gone with a joying at this point. If I decide I'm keeping it, I likely will upgrade to a joying.
