My Ford Mustang Sync 3 system was down for some time. Ford quoted me around $1100-1300. The diagnostic fee alone was $200. I reached out via the AI chat box and immediately someone helped me and speculated the API module had gone out because of my symptoms (black screen even on going in reverse, however speakers were working because the sensors were still active when in reverse). At first I was skeptical but decided to give it a shot. The person sent me a link to an installation video and it wasn’t too bad now looking back. Shipping was quick and I was provided shipping information right away. I will be purchasing again if my API goes out.
