The generic MOST adapter others sell here on Amazon WILL NOT FIT the stock connector in your vehicle without modification (cutting it up to make it fit). With this universal loop you can plug it in for testing/diagnostics/repair right out of the packaging without the fear of damaging it by attempting to trim it to fit yourself. 2. USA phone support. (If you don't believe us, just read the reviews). If for some reason you purchase this bypass and continue to have problems correcting your audio issue you may contact us and we will personally reach out to you by phone to troubleshoot your unique scenario and work with you to get the problem solved as quickly and cheaply as possible. 3. Some of our competitors use inferior fiber optics and and can cause intermittent connectivity issues in the optical network of your vehicle.
