I'm still dealing with my Sync2 system locking up and losing radio and Sync Functions. I called 4DTech who sell the new Sync2 to Sync3 upgrade system which I am considering and discussed my issues. I am on the trouble that requires the fuse # 79 R&R to restore normal function. He says most APIM's die with a black screen, which mine is not doing. When I paid Ford to diagnose this 18 months ago they said I needed a new radio module (ACM). BUT they 'got it working', obviously by R/R'ing fuse #79 and it worked fine for 18 months. So the DTech guy said that he felt I could still have a failing radio, but that (I shared the codes I pulled on FORscan: lost comms between APIM to Radio and Lost Comms between APIM and Sync) that he felt I a 60/40 APIM to ACM is failing. So here is my question, with the C-Max (or others) with Sync2 system, has anyone had a radio fail? Here is the link to the C-max upgrade, I will be selecting the non NAV kit and navigate on WAZE and Google Maps via Apple Play. https://www.4dtech.com/13-15-ford-c-max-sync-3-upgrade-for-myford-touch/#reviewsHeading THX Mark
