[Android Head-Units] magnuswf:
Hey everyone.

I've been tinkering most my life but I'm sort of new to all this android headunit stuff. I bought my Xtrons TR100 some years ago, and also asked a bit in here back then, but never got any further.

I decided to pick it up again, and I hope some of you can help me clear up some things.

I'm running audio to my 5ch amp via preouts, spotify and google maps on the unit locally, phone calls through BT, backup cam(Altho not connected right now)

My plans/wishes for my project are:

Better equalizer options than the Treble/Mid/Bass+Subwoofer+Fader/Balance - Maybe a launcher/firmware could help this? I've read about Viper4Android or something?

Faster response in general. I changed background from widget to plain black and cleared and updated some apps. Helped quite a bit, but maybe anything could help even more. - I've seen people put heatsinks and fans on the chip, and I'm thinking of doing that. Also, could newer/custom firmware help?

4g through sim datasharing sim card instead of wifi, if possible. - I saw some cables on Alibaba that connects to the white plugs like USB, but idk what antenna it would use then or if my unit supports that?

Dashcam is supported on the unit, but I fear the only 2gb ram and 26gb storage will make it very slow and fill up quickly, so maybe independent dashcam would be better.

Extend the display cable, so I can hide the unit itself deep in the dash, and 3D print a mount for the display for a better location.

I bought some headers in the correct spacing and size as the plug that goes on the board in the unit, so I assume I can just make an extension with a USB or Cat ethernet cable? They should be well insulated against EMI, right? Maybe two cables are needed side by side, if not enough wires.

Install external Wifi antenna, as I suspect the tiny antenna on the rear of the unit has bad signal buried deep inside my dash, but what antenna with cable is good for wifi? Similar to the ones used for Wifi MB's for pc, I would think?

Is it possible to DIY solder extra ram/swap the ram/flash storage for better chips/Swap the whole internal board for a better unit overall? I saw unit boards sold seperately on Aliexpress, so I'd think this could be possible instead of buying a brand new complete Headunit?

Capacitor/Stand alone battery mod for no-sleep for quick stops. I've seen some threads in here about those kind of mods.

Physical buttons, specifically volume know. Saw this device that simulates steering wheel buttons, and I thought I could DIY a step pot meter as volumeknob?

Some additional questions

1. Can you help me understand what components on my pictures are what? I assume the metal covered one is the cpu, and the XD-7786AF-0 I'm guessing is the fm reciever board? The rest I'm not sure about.

2. I see people here talking about FYT, MTCD and MTCB, but I've seen none of these letters in/on my unit, so how do i find out where to look?
