[FYT Android Head Units] Stefanek33:
Hi.

After purchassing Android 10 10.25inch screen for my mazda 6 skyactiv 2017 im running with couple off issue which i would like to put it right.

After spending days and hours to search on google to find the right answer i decide to post here as im running out of options and i just hoping someone smart and experinced will reply to my post..

I belive here are lot of smart people with full of experince and most likely this is the only forum when i can get the right answers and direction.

Im really sorry if my topic will be like Roman-Novel..Im just trying to provide as many information as possible.

Thank you for understanding!

So lets start.

So the Mazda 6 Sk 2017 bose system originally have stock 9 inch OEM screen with BT module ,TAU - tunner ampliefier unit which holds all inputs and then sending the signal into bose amp. Pictures included for detailed understanding.

Since the stock 9inch oem screen was replaced with the 10.25 android head unit with DSP chip when you keep the BT module and replace it only the stock 9inch OEM.Also bose amp was removed and replace it with DSP and SQ setup.But that just for information as it has nothing to do with a problems that occurs.

For information the android head unit cost me 650£ for those who may mention is maybe chinesse crap and advice to replace the unit..Unfortunatelly there is not android HU on the market with coax or digital output which will be compatible with my car.If there is i will not hacitate to go for it.

Now with the issues im running into it.

the main problem which driving me nuts is the interference im getting >here is bit older link for video how it is look like.:

Basically when you connect the android HU and run it you can switch within the original OEM infotaiment system and android HU..

it sending the signal into TAU -tuner amplifier unit (holding and controlling all inputs,CD,RADIO,AUX)

with a stock OEM all working fine without any interference etc.

With the android HU stock BT module where you controlling the sources CD,Radio all are fine.

But when you switch to AUX mode to make it work you have to connect the RCA at the back of the HU into TAU using aftermarket harness to make it work..Without connect it there will be no sound on AUX. (pictures included for the aftermarket harness)

Now the problem s you probabaly notice in the video is the interference im getting from the AUX source.

I did try lot of trials and errors.I also try ground loop isolator which result is down below in video but unfortunatelly this is not fix solution for a problem and i would only decide for it as a last option.

I also visit car electrician andhe advice me as ste stock OEM harness are shielded all over the place to avoid any interference and the aftermaret harness are china s..it without any shield.

We also did several test when we didnt connect the aux rca and just leave it unplugged ..There wasnt any static inteference at all.Only the hiss at max volume but we think that may be related to high gain on a amp.

So is that mean the aftermarket harness (pic included) its just poor and thats the main reason when i connect the harness backto the aux HU introducing the interference?

I been told to cut the rca on the harness and replace it with proper shilded one.Would that be solution and fix my problem.I dont know.I just dont want to make it worse.

If the chip on the HU have poor shilding it would not make any different if the rca are connected or not.The noise will be still in the present..Am i right?

WHat would you try to do in my situation?(Please just not silly ansfer like chuck the unit in a bin etc) thank you.

Problem N2:

Sometimes when i start the vehicle the stock OEM infotaiment system bootloader freeze and take good 1 min to kick on..Anyone know why thats happend?

Problem N3

Android FM radio no sound,hiss,Doesnt find any station at all.Search buttom doesnt work.

Stock OEM radio works fine.

Not any aditional fm plug from the andorid to the main harness..There are few wires but mainly related to the aftermarket rear camera..The others i dont know for what they are for.Somebody may know better.

Do you think the android have some special wires (picture included) which controling or actiwating the FM amp on the android HU?

That should be all .Im really sorry if is to long!

Only hope someone experienced will help.

Thank you.
