What future support do you mean?
I use it daily in my car, and if I find any glitches I fix them and provide update to community.
Also, I monitor user's reports for the same purpose.
Two or three bugs were fixed since very first version (the version 1.1 is the latest so far).
From the "number of features" perspective the software is completed, I think.
So if everything works for you now, you'll need no upgrades in future (except, I guess, if/when manufacturers roll the Android 5 out for our units - the SW part probably would need an update due to Android platform change).
Here's the risk: I will definitely not jump to Android 5 just to be "on the edge"; I will wait for it to stabilize on our units; and this, in turn, means that there would be no Android 5-compatible version at instant.
And to answer your last question:
I think they just don't care.
They get all the software from Microntek (whoever they are).
Microntek could make it already if they wanted to, without changing hardware at all, but they didn't.
Duh... My pics are more confusing than helpful. It's because I've made them while experimenting, and they really don't show the final mod. They mostly show the place where the soldering occurs.
So, let's maybe try with this short manual.
1. Find the Sound Processor, it's 28-lead IC marked BD37534FV, BD3702V or like that (different units use different analogs).
2. From leads 25 and 26 of it, using a multimeter, try to trace out the resistors connected to these leads.
3. Unsolder these resistors (on my photo, they're said to be removed), flip them 180 degrees and solder (place like two bigger resistors on the same photo), solder wires to free ends of the resistors.
4. Find the WM8731 IC on the board, it is also a 28-lead chip.
5. From leads 23 and 24 of this IC trace the resistors.
6. Solder other ends of wires to these resistors, to their ends that are opposite to WM8731. Refer to schematic: BD37X(25)-resistor-wire-resistor-WM8731(24) and BD37X(26)-resistor-wire-resistor-WM8731(23).
I've explained as clear as I could.
If it's no electrical incompatibility, I think this would a problem. Hopefully it's not(?)
I wonder whether the Sound Processor state isn't set at one time by the MCU (once, or when the Settings' Equalizer is changed) and then it could be changed/improved by your Equalizer, later, permanently.
