Optical cable change or not
Hi. i have a BMW f30 with harman system, and yesterday i installed an 10.25 android-10 SD625 HU, but the original sound sounds very fidelity, when I use android applications I lose a lot of fidelity. i dident move the optical cable from the original harness. Will I have to move it to the harness that is connected to the harman or does it not matter Thanks.
