Okay, so I’ve seen a couple threads on updating sync 3.0 to 3.4. And I figured I would try the update since I wasn’t crazy about the daytime screen options. I used Cyan Syn3 updater. And followed the instructions. I believe I saw others use this for their update, and it seemed pretty straight forward. My truck is a 2018. I plugged up USB and screen immediately went black and will not come back on. I realize these mods are at my own risk… so I don’t need any lectures. Lol I am wondering if anyone has any knowledge to get it back? I’ve pulled battery, and fuse. Did the power/seek button hold. And reset APIM in FORSCAN. Just wondering if someone has an idea, or is a new APIM Module in my future?
