2021 Eonon A0581 Optical Fiber Decoder Box Designed Only for GA9165A/GA9265B/GA9165B/GA9365/GA9465/GA9465B

Product worked. Should come with the stereo unit not extra. And way overpriced.

I needed this to adapt a new Eonon head unit to my Logic 7 system in my 2006 330Xi. Moving optical connection from OEM harness to this device was straightforward. When hooking up the 'input' RCA R/L audio cables -- remember these hook to the 'output' RCA cables from the head unit. I wish the device took in rear cables as well so that fade functionality would have been maintained -- but I can live without this.Note that I get an 'SOS' error with this device, because the MOST bus controller functionality is not maintained. I expected this -- and will need to get the error coded out.

Very easy to install will only plug in where it needs to b. Make sure u use the front RCA's out of the radio. It's not as loud but I think it gets loud enough and sounds clear.

Sound quality is good installation was easy, however it did not cover all of the requirements and this results in having to live with a SOS error on the BMW 335i 2008

Very dissapointed with the decoder. The front speakers appear to be getting the bass notes while the rear speakers are quiet. All speakers still work when connected to my eonon head unit (GA9465B). Can't fade from front to back. Basically, a loss of sound quality from stock. I wish Eonon would make a better fiber optic decoder to work with Logic 7.Update: I checked the wiring and the connections of the decoder and the head unit settings and now i think i got it to sound as loud as stock. Also for the rear speakers, i used some rca cable splitters to power the rear speakers. Rating updated to 3 stars.
