I purchased this Unit from amazon for my 2014 4runner on oct 22. When I first installed it The bluetooth audio from android auto would cut out randomley but that issue was resolved with a firmware update BUT the unit still has another major issue . There is a loud static noise that sounds like crackling that comes out of the right channel sometimes sometimes once in 30 minutes and sometimes right after i turn on the unit . The noise is NOT alternator whine and it is NOT a loose cable connection to an amplifier . This noise will go away if i use the am/fm radio. it will NEVER make the noise using radio , but as soon as i switch back to android auto the noise is back . Sometimes i can drive for 30 minutes without the noise before the noise comes back . The noise is present on music and the voice of the google assistant . I have tried 3 different versions of AVRCP bluetooth 1.4 , 1.5 and 1.6 and i have also tried 4 different audio codecs in the phone . I have also tried it with 3 different phones including A brand new 2024 samsung. It is my opinion that there is a Defective digital to analog converter in the bluetooth chip , or that the bluetooth chip or the D/A converter has a bad solder joint from manafacturing . I really want this radio to work . Do you have any suggestions other than returning it for a different Unit?
Also I wanted to say that the Unit Made the static scratching sound before I did the firmware update , but i had assumed that it was related to the bluetooth losing connection . The update fixed the lost connection but the loud static remains present
@Freddy S
Thank you for your kind reply.
Just would like to the static sound will happen on the local music?
Does it happen between Bluetooth connection and Android auto connection?
We thank you and look forward to your reply.
