Update on my situation: The high pitched whine ended to be a product defect. Mr. Bala from technocrat guided me to the nearest Nippon service and they tried replacing the Infotainment and the whine disappeared. Then AudioControl - LC6i - Line Output Converter was used and the amp reconnected. All seems well, except that I noticed that there is a slight hiss emerging at all times. This hiss is exactly the hiss that you hear when you turn the volume of a home stereo or amp all the way up when nothing is playing. This hiss is however not as obtrusive or irritating as the whine. Need to take the vehicle back to technocrat to ask them to check on what can be done. |

I have landed myself in similar problem. Put a 4 ch amp and new and then back to oem speakers its giving hissing sound and blue tooth mic creates lots of noise to caller. |
