Calothrix Posted March 1 Report Share Posted March 1 I just purchased a 2015 C-Max Energi SEL. Is there an easy way to determine if I have a 3G or 4G modem? Thanks! Quote Link to comment Share on other sites More sharing options...
cr08 Posted March 19 Report Share Posted March 19 (edited) My guess is it either has the 3G modem or the older 2G modem before that. 3G is more likely since that was a free upgrade but I have heard of a few rare cases where it wasn't done (and useless to do now. Ford won't even allow installation of the 3G modems now). 4G most seem to have skipped. Probably the easiest way to tell is download the FordPass app and add your VIN and it'll tell you either to activate the connectivity functions or it'll say the vehicle doesn't have it. There's also checking the modem ESN from the about screen in Sync but I can't recall which letters/numbers indicate which version offhand.
