I just got a new 2012 ford edge limited a few months ago and the Sync system has gone out. After attempting to reset by pulling the associated fuse, I think the APIM needs to be replaced. Is it worth it to upgrade from the Sync 2 system to the Sync 3 if I don't care about the Apple or Android Auto features, or navigation? I only care about restoring functionality for the heated seats and bluetooth phone connection for audio. If the audio and climate features all worked without the screen, I wouldn't even bother to replace it.
If the vehicle already has the 8" screen for the sync 2 system, will I still need a replacement screen to upgrade to the sync 3 system?
