Hello, I have a 2006 Toyota Camry XLE with the JBL AMP. I recently purchased the G13 unit for my model. I purchased the model with the JBL adapter. Everything went well until I noticed a speaker hum after powering on the radio. I also have a loud ground loop noise when the car is running. Any solutions to this issue?
I've tried updating the MCU firmware from the Dasaita website - Didn't help the issue.
