[QUOTE="JustAguy39, post: 8878129, member: 691639"] Hello all. At the beggining i would like to apologize for too long topic!But iwould like to provide as many information as i could! i posted i few forums and people seems to rather doesnt bother or doesnt want a waste a time. I decided to try for a last time. (I also ordered ground loop isolator which i will most likely use) If anyone here in this group have mazda 6 skyactiv year 2016 + with the bose system and TAU - tuner ampliffier unit and understand wiring diagrams that would only benefits to this topic. Mazda basically using the Original OEM infotaitment system and sending signal into TAU and afterwards process those signal into amp. I replace the old school screen with the android 10 10.25 screen with DSP built in when you keep the original BT module . All sources runing fine from the BT module into TAU and then into my system.There is no problem at all. .The android HU have AUX IN female rca on aftermarket harness.To have a sound trough the AUX the chinesse create aftermarket harness (red wire,pictures included) which one end you connect into TAU and the other end into OEM harness..From the AM harness there is loop and RCA LIN and RIN into the AUX IN on the android HU. Problem is when i connect them together i got this nasty interference noise. [URL unfurl="true"]https://vimeo.com/manage/videos/858445584[/URL] I try it also ground loop isolator and i will keep it like that if there is no solution. [URL unfurl="true"]https://vimeo.com/manage/videos/858446236[/URL] So the ground loop isolator do some job and completelly get rid of the interference..Yes there is some hum but that would be most likely related to the gain. I also try to bypass the TAU using laptop output with 3.5mm jack and 2RCA connected into ANDROID AUX IN..but unfortunatelly there is no sound and i dont know if there is possible way to connect speaker after the HU to test it if the noise comming from the AUX IN on the HU or is related to the poor RCA. I also bought better RCA but i dont want to cut them of and replace them if im not 100% sure that will solve the problem..Yes adding ground loop isolator on the poor chinasse RCA solve the problem but i still dont know if that problem is because of poor shielding or so. [URL unfurl="true"]https://www.amazon.co.uk/dp/B00SWYTT9E/[/URL] any idea where and what to check?Can that be related to ground loop issue ? All original mazda harness is shielded. i will include some pictures. i would apreciate any help. hope someone will reply! thank you [/QUOTE]
