2, What kind of car types/model might have "Audio delay problem"?
After we research and case study, the car with PANASONIC Radio Head unit with have this problem, also, if the car with Burmester sound system, it also have this problem. To handle this problem, it need to add a DSP module, to have the sound go to speaker directly (not go through USB), that way,the audio will not delay.
If your radio head unit is other brand, such as "MITSUBISHI" or "Harman Kardon", in most case, it don't have this problem.
